To find the equal angels, base angles, of an isosceles triangle and you know the vertex angle, 180-vertex angle and then divide by two.
yes it's base X height divide by 2 It's one-half the base x height. For example a triangle with a base of 10 cm and a height of 12 cm would have an area of 60 sq cm. (1/2 of 10 equal 5; 5 x 12 equal 60)
Try it out... Draw a triangle with 5 cm sides and see if you can make them fit.
Try 105/5 = 21
5 to the power of -2
