WebFeb 24, 2024 · 6. Add up the lengths of the three side lengths to find the perimeter. Recall that the perimeter P = a + b + c. Now that you know the lengths of sides a, b and c, you simply need to add the lengths together to find the perimeter. In our first example, P = 3 + 4 + 5, or 12. In our second example, P = 6 + 8 + 10, or 24 . WebJan 7, 2024 · At first (blue angles), notice how the A B C triangle is isosceles (since A B = B C ), and you get that the bottom angles are both 70 (because 180 − 40 2 = 70 ). Then, since B D ‖ A C, you can find that the angle next to the 40 º is also 70, and that the big angle that contains the x is 55.
