What is the definition of congruent triangles?

Back

Triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What additional information is required for two triangles to be congruent by SSS?

Back

The lengths of all three sides of both triangles must be known.

Front

How do you find the midpoint of a segment given two endpoints?

Back

Add the x-coordinates of the endpoints and divide by 2, then add the y-coordinates and divide by 2.

Front

What are the coordinates of the midpoint M of segment JL if J(2, -1) and L(-4, 3)?

Back

(-1, 1) is the midpoint.

Front

What is a polygon?

Back

A closed figure formed by a finite number of straight line segments.

Front

What is a quadrilateral?

Back
