Solved Examples on Isosceles Triangles. 1. Find the value of x in the given isosceles triangle ABC. Solution: In the given isosceles ∆ABC, AB = AC. Therefore, ∠ABC = ∠ACB = 75°. (Angle opposite to equal sides are equal) Now, ∠ABC + ∠BAC + ∠ACB = °. (Interior angle sum property of a triangle) 75° + x° + 75° = ° Isosceles right triangle - quick recap [HOST] GeoGebra #MTBoS #ITeachMath #math #maths #mathematics #geometry #mathteacher

Isosceles right triangle: In this type of isosceles triangle, two of the legs, and their corresponding angles, are of equal measure. Isosceles obtuse triangle: In this type of Missing: rdp In order to find the area of isosceles triangles, start with the area of a rectangle. The area of the rectangle is calculated by multiplying the \text {base } \times \text { height}. base × height. Within a rectangle, there is an isosceles triangle. It can be shown by drawing lines from a midpoint of the rectangle to the opposite vertices

Nancy Muchangwa, one of our Joburg DIY Divas, recently undertook a home improvement project to add on extra rooms to her RDP house. The original structure only had a bathroom with a small sink, a toilet, and a shower head fitting in the ceiling - with a hole in the floor for drainage. The home improvement project included added on a new An isosceles triangle is a special case of a triangle where 2 sides, a and c, are equal and 2 angles, A and C, are equal. In our calculations for a right triangle we only consider 2 known sides to calculate the other 7 unknowns Right Triangles. Hypotenuse equals twice the smallest leg, while the larger leg is 3–√ times the smallest. One of the two special right triangles is called a triangle, after its three angles. Theorem: If a triangle has angle measures 30∘, 60∘ and 90∘, then the sides are in the ratio x: x 3–√: 2x
