In order to answer this problem, you will need to know the definition of an isosceles triangle. An Isosceles triangle is specified as a triangle with 2 of its 3 sides having equal lengths. Step 1: Draw your triangle.
Step 2: Label your angles inside of your triangle.
Caution: The above statement ONLY applies to this type of triangle. Step 3: Write an equation. 100° + x° + x° = 180° Step 4: Solve for x. 100° + x° + x° = 180° 100° + 2x° = 180° 2x = 80° x = 40° The other angles in the obtuse isosceles triangle both equal 40°. |
