Unit 3A Midterm Review

Front

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but not necessarily the same size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

If two triangles are similar, what can we say about their corresponding sides?

Back

The lengths of their corresponding sides are proportional.

Front

What is the definition of slope in a linear equation?

Back

Slope is a measure of the steepness of a line, calculated as the rise (change in y) over the run (change in x).

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the slope of a line that goes down from left to right?

Back

The slope is negative.

Front

What is the slope of a line that goes up from left to right?

Back

The slope is positive.

Front

What does it mean to solve for x in an equation?

Back

To solve for x means to find the value of x that makes the equation true.

Front

If x + 5 = 10, what is the value of x?

Back

x = 5.

Front

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

Back

Area = 1/2 * base * height.

Front

What is the relationship between congruent figures?

Back

Congruent figures are identical in shape and size; all corresponding sides and angles are equal.
