What does it mean for ray AD to bisect angle CAB?

What is the SSS postulate in triangle congruence?

Back

The SSS (Side-Side-Side) postulate states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

How do you solve for x in the equation 2x + 3 = -5?

Back

Subtract 3 from both sides: 2x = -8. Then divide by 2: x = -4.

What is the rule for reflecting a point across the line x = 3?

Back

To reflect a point across the line x = 3, you measure the distance from the point to the line and place the reflected point the same distance on the opposite side.

Front

What does it mean for two angles to be congruent?

Back

Two angles are congruent if they have the same measure.

Front

What is the SAS postulate in triangle congruence?

Back

The SAS (Side-Angle-Side) postulate states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

How do you find the measure of an angle if you know the measures of the other two angles in a triangle?

Back

Use the triangle sum theorem: the sum of the angles in a triangle is 180 degrees. So, if you know two angles, subtract their sum from 180 to find the third angle.

Front

What is the definition of a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is the ASA postulate in triangle congruence?

Back

The ASA (Angle-Side-Angle) postulate states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.
