Geometry Review - 2

Front

Find the missing angle in a triangle if two angles measure 28° and 34°. What is the third angle?

Back

The third angle is 118° because the sum of the interior angles of a triangle is always 180°.

Front

What is the sum of interior angles of a triangle?

Back

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

Front

Find the measure of the indicated angle if one angle is 90° and the other is 54°. What is the third angle?

Back

The third angle is 36° because the sum of the angles in a triangle is 180°.

Front

If lines are parallel and a transversal intersects them, what are the angles in the same position called?

Back

The angles in the same position are called Corresponding Angles.

Front

If lines are parallel and a transversal intersects them, what are the angles that lie outside the parallel lines but on opposite sides of the transversal called?

Back

The angles are called Alternate Exterior Angles.

Front

What is the relationship between the angles formed when two parallel lines are cut by a transversal?

Back

The angles formed have specific relationships: Corresponding Angles are equal, Alternate Interior Angles are equal, and Same-Side Interior Angles are supplementary.

Front

What is the measure of each angle in an equilateral triangle?

Back

Each angle in an equilateral triangle measures 60°.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180°.

Front

What is the definition of vertical angles?

Back

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

Front

If two angles are complementary, what is the sum of their measures?

Back

The sum of the measures of complementary angles is 90°.
