![]() ![]() Once you have completed these steps, you should now have an isosceles right triangle □. Repeat the above step from point b to point c.Use your ruler and pencil to draw a line from point a to c.Name the point where the arc passes through the perpendicular line c.Place your compass at o and draw an arc that cuts line ab at both ends and the perpendicular line at one end.Label the point where the two lines now bisect each other, o.Using your ruler and pencil, draw a line through the points where the arcs intersect.These two arcs should intersect at the top and bottom. Place your compass on point b and, extending the drawing end a little beyond the center of the line, draw another large arc as you did before.Draw a point on the other end of the line with your pencil.Place your compass on the point marked a, and extending the drawing end a little beyond the center of the line, draw an arc that cuts through the line and extends upwards, creating a half-circle. ![]() Use your ruler to draw a horizontal line on the page.Hence, by the formula, A 1/2 x b x h, we can derive the formula for the area of the isosceles triangle by the formula given below: Area of isosceles. A perpendicular is drawn from A to D which divides the base into 2 equal parts. Now that you have the tools you need, let's get started: In the figure given below, we have an isosceles triangle with two equal sides, ‘a’ and the base as ‘b’. area of which is of course obtained by multiplying together the numbers representing the sides. For example, given a triangle with leg length 8 and base length 6.5, the altitude must be: sqrt (82 - (6.5 / 2)2 sqrt (53.4) 7.3. The area of an isosceles triangle can be easily derived using Heron’s formula as explained below. To construct a right isosceles triangle, you will need your book, a ruler, and a compass. To find the altitude of an isosceles triangle with a known leg length and base length, use the following formula: sqrt (L2 - (B / 2)2, where L is the leg length and B is the base length.
