**In an isosceles triangle, the base angles are congruent. **

**Use the formula to calculate the height of an equilateral triangle. **

**The term " base" denotes any. The legs of either right triangle formed by an altitude of the equilateral triangle are half of the base , and the hypotenuse is the side of the equilateral triangle. **

**Find the base and the height if the area of the triangle is 14 in^2. **

**Recall from above that an equilateral triangle is also an isosceles triangle. **

**Suppose each side of the base is a and each slant edge is s. To find the height we divide the triangle into two special 30 - 60 - 90 right triangles by drawing a line from one corner to the center of the opposite side. The height is equal to side/2 x √3. **

**While solving different questions , I realized that whenever I constructed an altitude it always bisected the base in half. **

**. Declare 3 double type variables, each representing one of three sides of a triangle. if the base is a square, we can. **

**Finding area of triangles. The base of a triangle is 1 in more than twice the height. **

**h = 3 2 a = 3 2 × 5 u n i t s = 4. **

**. **

**. . **

**. /√3. **

**Three right angles are also equal in size since their opposite sides are also equal in length.**** An equilateral triangle is a triangle with all three sides equal and all three angles equal to 60\degree 60°. **

**. **

**a 2 = h 2 + (a/2) 2. Height of the equilateral triangle is derived by splitting the equilateral triangle into two right triangles. Area of an Equilateral Triangle. **

**The general formula for the area of a triangle whose base and height are known is given as:. . All three angles are the same. H n = a 2 6 + a 2 3 2 = 4 a 2 6 = a 2 3. Triangle missing side example. **

**The tetrahedron is a triangular pyramid having congruent equilateral triangles for each of its faces. **

**The term " base" denotes any. Equilateral triangles are triangles that have all of their sides with the same length. **

**An equilateral triangle has three congruent sides, and is also an equiangular triangle with three congruent angles that each meansure 60 degrees. **

**And each pyramid has the same volume abc/6. **

**Area of right triangles. **

**Now, apply Pythagoras Theorem in the triangle. **

**There are three variations to the same formula based on which sides and included angle are given. **
