These congruence rules can actually be derived by introducing additional concepts, so we do not really need to take them as axioms. However, I would rather not spend time on this (proof of SSS takes some time), so I decided to take them as axioms. 6. ISOSCELES TRIANGLES WebThe area of an isosceles triangle is given by the following formula: Area (A) = ½ × base (b) × height (h) The perimeter of the isosceles triangle is given by the formula: Perimeter (P) = 2a + base (b) Here, ‘a’ refers to the length of the equal sides of the isosceles triangle and ‘b’ refers to the length of the third unequal side.
