Learn how to find out the angles of a picture of triangles.
- Isosceles Triangle Definition - An explanation of isosceles triangles and what that means for the triangle.
- 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.
