Answer: Any isosceles triangle is a counter example. More specifically, a triangle with sides 7, 7 and 3
When forming your triangle, make sure you apply the triangle inequality theorem. This is the idea where adding any two sides leads to a result larger than the third side. So we have
7+7 = 14 which is larger than 3
7+3 = 10 which is larger than 7
By definition, an isosceles triangle has two congruent sides. Some books say "at least 2 congruent sides", but I'll go with the first definition. If you want all three sides to be congruent, then you'd go for the term "equilateral".
Ok I can help just tell me the problem
Answer:
63
Step-by-step explanation:

12 x 3 = 36
99 - 36
= 63
Answer:
192 hours.
Step-by-step explanation:
24 hours in a day
24 x 8 = 192 hours.
The answer is 7, 2(7x5) + 2(4x7) + 2(5x4) = 166
