# Lesson 10

Drawing Triangles (Part 2)

### Problem 1

A triangle has sides of length 7 cm, 4 cm, and 5 cm. How many unique triangles can be drawn that fit that description? Explain or show your reasoning.

### Solution

For access, consult one of our IM Certified Partners.

### Problem 2

A triangle has one side that is 5 units long and an adjacent angle that measures $$25^\circ$$. The two other angles in the triangle measure $$90^\circ$$ and $$65^\circ$$. Complete the two diagrams to create two different triangles with these measurements.

### Solution
