### Finding angles in isosceles triangles (video) Khan Academy

The sum of angles in a triangle are 180, and if you have an iscoseles triangle, the angles opposite the congruent sides are congruent also. So if you have x as one of the angles opposite and a vertex angle of x + 30, the other opposite angle is also x, so x + x + x+ 30 = 180 which you can solve. How to Calculate the Sides and Angles of Triangles Oct 20, 2020 · Answer:Since the triangle is equilateral, all the angles are 60 degrees. However, the length of at least one side must be known. Once you know that length, since the triangle is equilateral, you know the length of the other sides because all sides are of equal length.

### How to Find the Altitude of a Triangle (Formula & Examples

a2 + 144 = 576 a 2 + 144 = 576. a2 = 432 a 2 = 432. a = 20.7846 yds a = 20.7846 y d s. Anytime you can construct an altitude that cuts your original triangle into two right triangles, Pythagoras will do the trick! Use the Pythagorean Theorem for finding all altitudes of all equilateral and isosceles triangles. Polygons - TrianglesThe measure of the central angles of an equilateral triangle:To find the measure of the central angle of an equilateral triangle, make a circle in the middle A circle is 360 degrees around Divide that by three angles So, the measure of the central angle of an equilateral triangle is 120 degrees.
