1 Special Shortcuts for 45-45-90 and 30-60-90 Triangles

2 45-45-90 Triangle If you know the length of the leg, multiply that by 2 to find the length of the hypotenuse.

3 Do problems 1-3 on handout

4 45-45-90 Triangle If you know the length of the hypotenuse and you want the length of the leg, divide the length of the hypotenuse by 2.

5 Do problems 4-6 on handout

6 30-60-90 Triangle When working with a 30-60-90 triangle, you will have three different lengths: Short leg Long leg Hypotenuse

7 30-60-90 Triangle If you know the length of the short leg: The length of the hypotenuse is twice the length of the short leg. The length of the long leg is the length of the short leg multiplied by 3.

8 Do problems 7-9

9 30-60-90 Triangle If you know the length of the hypotenuse: Find the length of the short leg by dividing the length of the hypotenuse by 2. Now that you know the length of the short leg, multiply it by 3 to find the length of the long leg.

10 Do problems 10-12

11 30-60-90 Triangle If you know the length of the long leg: Find the length of the short leg by dividing the length of the long leg by 3. Now that you know the length of the short leg, multiply it by 2 to find the length of the hypotenuse.

12 Do problems 13-15
