# Question: 3 if the perimeter of a triangle is 15 and...

###### Question details

3. If the perimeter of a triangle is 15, and two of the side lengths are 3 and 8, can the triangle be isosceles?

4. Given: Triangle ABC is isosceles; angle A is 110 degrees; the length of side BC is 6; the length of side CA is 4. What is the perimeter of triangle ABC?

1. If two angles in a triangle have a measure of 60 degrees, what is true about the sides of that triangle?
2. Is it ever possible for a triangle to be either equilateral or equiangular and not the other?

7. Decide whether the triangle below is a 30-60-90 triangle, a 45-45-90 triangle, a right triangle with different angle measures than these, or not a right triangle at all. 1.
