Question

Find the perimeter of an isosceles triangle , an equilateral triangle and scalene triangle ​

Answer 1

Answer:

if a,B are sides of isosceles triangle a+2B

Step-by-step explanation:

for scalene a+b+c

Answer 2

Answer:

$\textsf{To calculate the perimeter of an isosceles triangle, the expression 2s + b is used, where s represents the length of the two congruent sides and b represents the length of the base.b) A scalene triangle : It has all the sides unequal.</p><p>∴ perimeter = x+y+z</p><p>Where x,y and z are the sides of a scalene triangleSince an “equilateral” triangle has three sides of the exact same length, its perimeter is three times the length of an side. An equilateral triangle has all its three sides and angles equal. The perimeter of an equilateral triangle = l + l + l = 3l, where, l is each side of the equilateral triangle (P = 3l)..}$
