An isosceles triangle is a triangle that has any two sides equal in length and angles opposite to equal sides are equal in measure. The perimeter of an isosceles triangle is 2a + b. Learn properties at BYJU’S.
Moreover, since the lengths of all sides are known, we can use the Perimeter Formula for a triangle: P=a+b+c We then substitute the given lengths to the formula to get: P=4 units+3 units+5 units Afterward, we add the numbers to obtain the value of the perimeter: ...
collection of triangles. Also, trigonometry has astoundingly intricate relationships with other branches of mathematics like in complex numbers, infinite series, logarithms, and calculus. The solution for an oblique triangle can be done with the important sine formula and cosine formula of the ...

Here, we're told that the base of our triangle is 5 and the height is 6. To find the area, then, all we need to do is plug these numbers into the area formula as so: A=12bh A=12(5)(6) A=15 This gives usan area of 15 square units for the triangle. This is a fairly st...
