Angle Relationships & Angles of a Triangle Review (G326 - BFA)

Front

What are same side exterior angles?

Back

Same side exterior angles are pairs of angles that are on the same side of a transversal and outside the two lines it intersects.

Front

What is the value of x if 2x + 4 = 16?

Back

x = 6

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two different parallel lines cut by a transversal.

Front

How do you find the measure of an angle in a triangle?

Back

The sum of the interior angles of a triangle is always 180°. To find an unknown angle, subtract the sum of the known angles from 180°.

Front

What is a right isosceles triangle?

Back

A right isosceles triangle is a triangle that has one 90° angle and two sides of equal length.

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are equal when two parallel lines are cut by a transversal.

Front

What is the sum of the angles in any triangle?

Back

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

Front

What are vertical angles?

Back

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

Front

How do you identify complementary angles?

Back

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

Front

What is the definition of supplementary angles?

Back

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