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
Divide the base of the triangle into five equal lengths. Draw lines from the opposite vertex to each of these dividing points. The triangle will be divided into five parts, each with the same area. The base is 1/5 of the original base, and they all have the same height - the same as in the original triangle.

If all the sides are equal to 5 cm, then it's a equilateral triangle. An equilateral triangle is a triangle in which all the sides are equal.
no there is no way to correctly divide a triangle into three equal parts. One side will always turn out an inch or so larger.
There are an infinite number of lines that can divide a triangle into two parts with equal areas. The medians are one set of such lines.

Select any one side and divide its length into 5 equal parts. Draw lines that are parallel to the adjacent side to the opposite side. This will divide the rectangle into 5 equal strips.
A pentagonal pyramid.
An isosceles triangle is a triangle that has two congruent or equal sides. For example, a triangle that has sides of 3,3, and 5.
5 cm2
If all sides of a triangle are of equal length, then all the angles are the same. The sum of the angles of a triangle is 180 degrees. If all 3 angles are the same, divide 180 by 3 = 60 degree angles.
No but the sum of the squared sides will equal the square of the hypotenuse using Pythagoras' theorem for a right angle triangle
