How to solve
This quiz mixes questions from different lessons, like a real test. Read each question carefully: the lesson name in front tells you what kind of problem it is. Check your answers, then practise the lessons where you made mistakes.
Example
Types of Angles: Acute, Right, Obtuse, Straight, Reflex & Full Turn: Classify an angle of 23°: acute, right, obtuse, or straight?
Answer: acute

💡 Exactly 90° is a square corner, so it is a right angle.
✓ Correct!
Not quite. The answer is
💡 Exactly 90° is a square corner, so it is a right angle.
💡 How to solve: Types of Angles: Acute, Right, Obtuse, Straight, Reflex & Full Turn
An acute angle is less than 90°. A right angle is exactly 90°, a square corner. An obtuse angle is more than 90° but less than 180°. A straight angle is exactly 180°, a straight line. A reflex angle is more than 180° but less than 360°. A full turn is exactly 360°, all the way around. Two angles that make a right angle add to 90°, a straight angle 180°, and a full turn 360°, so subtract to find a missing part.

💡 A rectangle needs 4 right angles. A rhombus with 4 right angles (a square) is a rectangle, but a slanted rhombus is not, so the answer is sometimes.
✓ Correct!

💡 A rectangle needs 4 right angles. A rhombus with 4 right angles (a square) is a rectangle, but a slanted rhombus is not, so the answer is sometimes.
💡 How to solve: Classifying Quadrilaterals & Triangles
Every square is a rectangle and a rhombus, and every rectangle and rhombus is a parallelogram, because it has all of their properties. Give the most specific name that fits. A triangle is right if one angle is 90°, obtuse if one angle is more than 90°, and acute if all three angles are less than 90° (the angles always add up to 180°).

💡 The third side is 20 − 8 − 7 = 5 units. So the sides are 8, 7 and 5. All three sides are different lengths, so it is scalene.
✓ Correct!
Not quite. The answer is
💡 The third side is 20 − 8 − 7 = 5 units. So the sides are 8, 7 and 5. All three sides are different lengths, so it is scalene.
💡 How to solve: Classifying Shapes
Compare the three side lengths. If all three are equal, the triangle is equilateral; if exactly two are equal, it is isosceles; if no sides are equal, it is scalene.

💡 One layer is 3 cubes long and 3 cubes deep: 3 × 3 = 9 cubes. There are 2 layers, so 9 × 2 = 18. The answer is 18 cubic units.
✓ Correct!
Not quite. The answer is
💡 One layer is 3 cubes long and 3 cubes deep: 3 × 3 = 9 cubes. There are 2 layers, so 9 × 2 = 18. The answer is 18 cubic units.
💡 How to solve: Volume: Unit Cubes & Composite Solids
Volume counts the unit cubes that fill a solid: one layer holds length × width cubes, and there are height layers, so V = l × w × h = B × h (B is the area of the base). For a solid made of two rectangular prisms, find the volume of each prism and add them.

💡 The bottom layer is 2 cubes long and 4 cubes wide: 2 × 4 = 8. The answer is 8.
✓ Correct!
Not quite. The answer is
💡 The bottom layer is 2 cubes long and 4 cubes wide: 2 × 4 = 8. The answer is 8.
💡 How to solve: Volume by Counting Cubes
Volume is the number of unit cubes that make the solid. For a box, count one layer (length × width) and multiply by the number of layers: 4 × 3 × 2 = 24 cubic units. For a staircase shape, count the cubes in each stack (how tall it is) and add the stacks; the cubes under the top ones are there even though you cannot see them.

💡 The y-coordinate tells how far up P is. Look straight across from P to the y-axis (the line up the left side): it is level with 5. P is at (1, 5), so the y-coordinate is 5.
✓ Correct!
Not quite. The answer is
💡 The y-coordinate tells how far up P is. Look straight across from P to the y-axis (the line up the left side): it is level with 5. P is at (1, 5), so the y-coordinate is 5.
💡 How to solve: Coordinate Plane (Quadrant I)
A point is written as (x, y): x tells how far right to move from the origin and y tells how far up. The x-coordinate is always the first number and the y-coordinate is the second, so write your point as (x, y).

💡 Area = length × width = 37 × 45. Multiply the numerators: 3 × 4 = 12. Multiply the denominators: 7 × 5 = 35. That gives 1235. 1235 is already in simplest form. The area is 1235 square inches.
✓ Correct!

💡 Area = length × width = 37 × 45. Multiply the numerators: 3 × 4 = 12. Multiply the denominators: 7 × 5 = 35. That gives 1235. 1235 is already in simplest form. The area is 1235 square inches.
💡 How to solve: Area with Fraction Side Lengths
Area = length × width, even when the sides are fractions. Multiply the numerators and multiply the denominators, then simplify. For mixed numbers, change them to improper fractions first. In a tiled unit square, count the shaded small rectangles and put that over the total number of small rectangles.

💡 The three angles add up to 180°, so the third angle is 180° − 43° − 114° = 23°. One angle, 114°, is more than 90°, so it is an obtuse triangle.
✓ Correct!
