Transversals and Angles of Triangles

Front

What are transversals in geometry?

Back

Transversals are lines that intersect two or more other lines at distinct points.

Front

What are congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

What are supplementary angles?

Back

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

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

If two angles are alternate interior angles, what can be said about their measures?

Back

If two angles are alternate interior angles, they are congruent.

Front

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

Back

Corresponding angles are congruent when two parallel lines are cut by a transversal.

Front

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

Back

Subtract the sum of the known angles from 180 degrees.

Front

What is the ratio of the interior angles of a triangle with measures 3:5:7?

Back

The angles measure 36 degrees, 60 degrees, and 84 degrees.

Front

What is the measure of angle B if angle A is 118 degrees in a triangle?

Back

Angle B is 62 degrees.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect, and they are congruent.
