Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

If ∠A and ∠B are complementary and m∠A = (3x)° and m∠B = (5x + 6)°, what equation represents their relationship?

Back

7x + 6 = 90

Front

What does it mean if two angles are congruent?

Back

Two angles are congruent if they have the same measure.

Front

If ∠ABD ≅ 2(∠ABC), what can we conclude about the relationship between these angles?

Back

∠ABD is twice the measure of ∠ABC.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run.

Front

How do you determine if two triangles are similar?

Back

Triangles are similar if their corresponding angles are equal or their sides are in proportion (SSS, SAS, or AA similarity criteria).

Front

What does SSS similarity mean?

Back

SSS similarity means that if the three sides of one triangle are proportional to the three sides of another triangle, then the triangles are similar.

Front

What is the formula for finding the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

If m∠A = (3x)° and m∠B = (5x + 6)°, what is the value of x if they are complementary?

Back

x = 6.

Front

What is the relationship between angles if ∠1 ≅ ∠2 is false?

Back

It means that ∠1 and ∠2 do not have the same measure.
