Geom Week 10 PT SAT Skill Check

Front

What is the sum of the angles in a triangle?

Back

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

Front

If two lines are parallel, what can be said about the angles formed when a transversal crosses them?

Back

When a transversal crosses parallel lines, corresponding angles are equal, and alternate interior angles are equal.

Front

What is the definition of corresponding angles?

Back

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

Front

What is the definition of alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two parallel lines.

Front

If angle 1 is 38 degrees, what is the measure of angle 2 if lines l and m are parallel?

Back

Angle 2 measures 142 degrees.

Front

In a triangle, if one angle is 57 degrees and the other is 76 degrees, what is the measure of the third angle?

Back

The third angle measures 47 degrees.

Front

What is the relationship between the angles in a right triangle?

Back

In a right triangle, one angle is 90 degrees, and the sum of the other two angles is 90 degrees.

Front

If line AB is parallel to line CD, what can be said about the angles formed with a transversal?

Back

The angles formed with a transversal will have corresponding angles that are equal and alternate interior angles that are equal.

Front

What is the measure of angle ACB if line BC is parallel to line DE and angle ACB is an exterior angle?

Back

Angle ACB measures 27 degrees.

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.
