## Draw a circle with the center at the origin and a radius of 2. Draw another circle with center at the origin and a radius of 3. Construct a 40 degree angle with the vertex at the origin that is in the first quadrant. Label the vertex A.

## Draw a circle with the center at the origin and a radius of 2. Draw another circle with center at the origin and a radius of 3. Construct a 40 degree angle with the vertex at the origin that is in the 2nd quadrant. Label the vertex A.

What is an included angle?

What is information is given about the triangles that were constructed?

What can we conclude about the two triangles that were constructed.

If we have two triangles such that we know that two pair of corresponding sides are congruent and the pair of included angles are congruent, then what can we say about the triangles?
