- Area: Triangle vs. Rectangle
- Why is the formula for the area of a triangle different from that of a rectangle or square?

- Perimeter Equals Area in a Triangle
- When will the area and perimeter of a right triangle be numerically equal?
- Right Triangles
- Is there an easy way to remember the different right triangles and how to find the length of missing sides? I already know that in any right triangle: (a*a) + (b*b) = (c*c).
- Triangles: Height and Angle
- A tree casts a shadow 30 ft and makes an angle of 47 degrees with the ground. How high is the tree?
- Why do the angles of a triangle add to 180 degrees?
- We were wondering why all the angles in a triangle add up to 180 degrees.
- Teaching Area of Triangles
