Prep Geo Unit 4 Test Review 1

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning their corresponding sides and angles are equal.

Front

If \( \Delta BIG \cong \Delta LAD \), which angles are congruent?

Back

The corresponding angles of the two triangles are congruent. For example, if \( \angle D \) corresponds to \( \angle G \), then \( \angle G \cong \angle D \).

Front

How do you determine the value of x in an equation?

Back

To determine the value of x, isolate x on one side of the equation using algebraic operations such as addition, subtraction, multiplication, or division.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is the definition of an angle?

Back

An angle is formed by two rays (sides) that share a common endpoint (vertex).

Front

How do you find the measure of an angle when given its complement?

Back

The measure of an angle and its complement add up to 90 degrees. If the complement is known, subtract it from 90 to find the angle.

Front

What is the relationship between corresponding angles in congruent triangles?

Back

Corresponding angles in congruent triangles are equal.

Front

What does it mean for two angles to be complementary?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

What is the definition of a vertical angle?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

How do you identify corresponding sides in congruent triangles?

Back

Corresponding sides in congruent triangles are the sides that are in the same position relative to the angles.
