Front

Can the following side measures form a triangle? 4 cm, 7 cm, 10 cm

Back

Yes, a triangle can be formed if the sum of the lengths of any two sides is greater than the length of the third side.

Front

What is a perpendicular bisector?

Back

A perpendicular bisector is a line that divides a segment into two equal parts at a 90-degree angle.

Front

What is the circumcenter of a triangle?

Back

The circumcenter is the point where the perpendicular bisectors of the sides of a triangle intersect.

Front

List the angles in order by measure, smallest to largest: ∠A, ∠B, ∠C

Back

∠A, ∠C, ∠B (assuming ∠A < ∠C < ∠B).

Front

If CP = 16, what is CL if CL is twice CP?

Back

CL = 32.

Front

What is the triangle inequality theorem?

Back

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

Define altitude in a triangle.

Back

An altitude is a perpendicular segment from a vertex to the line containing the opposite side.

Front

What is an angle bisector?

Back

An angle bisector is a ray that divides an angle into two equal angles.

Front

What is the incenter of a triangle?

Back

The incenter is the point where the angle bisectors of a triangle intersect, and it is the center of the triangle's incircle.

Front

What is a midsegment in a triangle?

Back

A midsegment is a segment that connects the midpoints of two sides of a triangle.
