2D Space — Level 5
Match attributes - sides and angles - to triangle type - equilateral, isosceles or scalene triangle. Measure the length of the sides, and the angles, of each triangle and write the type of triangle. Find the third angle by subtracting the sum of the two given angles from 180 degrees. Why is an equilateral triangle also an isosceles triangle?
