Taught by MrRutter

### Meets NCTM Standards:

Learn how to find out the angles of a picture of triangles.
• How do find angles if you have a picture with a bunch of triangles touching each other?
• How do you find the angle measures if you just have a picture with tick marks?
• How do you find angle measures in a picture with isosceles and equilateral triangles bunched together?
• What is each angle measure in an equilateral triangle?
• How many degrees are in a straight line?
• If you know two angles in a triangle, how do you find the third angle?
• If you know one angle in an isosceles triangle, how do you find the other two?
• How do you find angle measures in a diagram if you do not start with any angle measures?
This video finishes off the problem introduced in Part 1 of Isosceles Triangles. This is a rather daunting problem at first glance, and it uses a lot of prior knowledge about angles and isosceles triangles. This is a great wrap-up problem to a section on angles and triangles.
