Front

Name the angles from SMALLEST to LARGEST: ∠Q, ∠R, ∠P

Back

∠R, ∠P, ∠Q

Front

If CF, BE, and AD are the medians of the triangle and BF = 10, find AF.

Back

AF = 10

Front

What is the first step of an indirect proof?

Back

Assume the negation of what you are trying to prove.

Front

Point A is the incenter of \(\Delta PQR\). Find each measure of \(\angle YLA\).

Back

32

Front

If m∠CAP = 34°, find ∠CAB.

Back

∠CAB = 68°

Front

Define a median in a triangle.

Back

A median is a line segment joining a vertex to the midpoint of the opposite side.

Front

What is the sum of the interior angles of a triangle?

Back

180°

Front

Explain the concept of an incenter in a triangle.

Back

The incenter is the point where the angle bisectors of a triangle intersect, and it is equidistant from all sides.

Front

What is the relationship between the angles in a triangle?

Back

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

Front

Define indirect proof.

Back

An indirect proof is a method of proving a statement by assuming the opposite is true and showing that this assumption leads to a contradiction.
