How to measure a triangles perimeter?
You find the three sides of the triangle, and assure that they are all in the same unit, and then add the sides together to find the perimeter of the triangle.
How do you find the perimeter of congruent triangles?
Just add up together their 3 sides
How do you find perimeter and area of triangles?
Perimeter . . . add up the lengths of all three sides. Area . . . multiply (half the length of the base) by (the height).
The sum of the perimeters of two congruent triangles is three times the perimeter of the first triangle?
Let's denote the perimeter of the first triangle as P. Since the triangles are congruent, the perimeter of the second triangle is also P. The sum of their perimeters is then 2P. According to the given statement, this sum is three times the perimeter of the first triangle. So we have the equation 2P = 3P. Simplifying, we find that P = 0, which is not a valid solution. Therefore, there is no triangle for which the sum of the perimeters of two congruent triangles is three times the perimeter of the first triangle.
If two triangles have the same perimeter will they have the same area?
