Front

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a criterion for triangle congruence that applies to right triangles.

Front

What is the formula to find the number of sides in a regular polygon given an exterior angle?

Back

The formula is: Number of sides = 360° / Exterior angle.

Front

If SR = 68, what is the relationship between SR and CA if CA is half of SR?

Back

CA = SR / 2 = 34.

Front

What are the properties of a parallelogram?

Back

In a parallelogram, opposite sides are parallel and congruent, and opposite angles are congruent.

Front

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

Back

Use the formula: Measure of the third angle = 180° - (Angle 1 + Angle 2).

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence where two sides and the included angle are known.

Front

What is the measure of each exterior angle of a regular polygon with 10 sides?

Back

Each exterior angle measures 36°.

Front

What is the sum of the interior angles of a polygon with n sides?

Back

The sum of the interior angles = (n - 2) × 180°.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruence where two angles and the included side are known.

Front

What is the relationship between the angles in a triangle?

Back

The sum of the angles in a triangle is always 180°.
