8th grade Math Review 3

Front

What is the solution to the equation 7a + 1 + 3 = 18?

Back

a = 2

Front

Solve for x: -12 + 4x + 10 = 14

Back

x = 4

Front

What transformation is represented by a rotation of 180 degrees?

Back

A rotation of 180 degrees flips the figure around a point, resulting in a figure that is upside down.

Front

Which of the following is NOT a rigid motion: Rotation, Reflection, Translation, or Dilation?

Back

Dilation is NOT a rigid motion because it changes the size of the figure.

Front

What is the solution to the equation 3b + 6b = 63?

Back

b = 7

Front

Define a rigid motion in geometry.

Back

A rigid motion is a transformation that preserves distance and angle measures, such as rotation, reflection, and translation.

Front

What is the formula for finding the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same shape and size.

Front

What is the difference between a reflection and a rotation?

Back

A reflection flips a figure over a line, while a rotation turns a figure around a point.

Front

How do you solve the equation 4x - 5 = 11?

Back

Add 5 to both sides to get 4x = 16, then divide by 4 to find x = 4.
