Triangle Midsegment and CPCTC Flashcard

Front

What is a midsegment in a triangle?

Back

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

Front

What is the Triangle Midsegment Theorem?

Back

The Triangle Midsegment Theorem states that the midsegment of a triangle is parallel to the third side and is half its length.

Front

If segment AB is a midsegment of triangle CDE, what can be said about segment DE?

Back

Segment AB is parallel to segment DE and its length is half the length of segment DE.

Front

What does CPCTC stand for?

Back

CPCTC stands for 'Corresponding Parts of Congruent Triangles are Congruent'.

Front

How can you determine if two triangles are congruent?

Back

Two triangles can be determined to be congruent if they satisfy any of the congruence criteria: SSS, SAS, ASA, AAS, or HL.

Front

What is the relationship between angles in congruent triangles?

Back

In congruent triangles, corresponding angles are equal.

Front

If triangle ABC is congruent to triangle DEF, what can be said about angle A and angle D?

Back

Angle A is equal to angle D.

Front

What is the significance of parallel lines in triangle midsegments?

Back

Parallel lines in triangle midsegments indicate that the segments are proportional and help in establishing congruence.

Front

If the midsegment of a triangle measures 6 cm, what is the length of the side it is parallel to?

Back

The length of the side it is parallel to is 12 cm.

Front

What is the formula to find the length of a midsegment?

Back

The length of a midsegment is half the length of the side it is parallel to.
