Question

Найдите периметр равнобедренного треугольника ADC с основанием AD, если AD = 7 см,DC = 8 см.

Answer 1

 

Сторона АС = ДС (тр-к равнобедренный)

Периметр тр-ка Р = АД + АС + ДС = 7 + 8 + 8 = 23(см)

Answer 2

Т.к. АД основание, то DC и AC - боковые грани, при чем если треуольник равнобедренный, то DC=AC=8

P=7+8+8=23

Answer 3

Perimeter of a Isosceles Triangle ADC

To find the perimeter of a triangle ADC with base AD and sides AD = 7 cm and DC = 8 cm, we need to add the lengths of all three sides.

The triangle ADC is an isosceles triangle, which means that two sides (AD and DC) are equal in length. The base AD is not equal in length to the other two sides.

To find the perimeter, we add the lengths of all three sides:

Perimeter = AD + AD + DC

Substituting the given values:

Perimeter = 7 cm + 7 cm + 8 cm

Perimeter = 22 cm

Therefore, the perimeter of the triangle ADC is 22 cm.
