Will you help me with this math problem?

Question

If 2 angles of a triagle each measures 70 te triangle is described as...

a) scalene
b) obtuse
c) isosceles
d) right

Answer 1

equilateral triangle - all sides/angles are of equal length
isosceles triangle - two sides/angles are of equal length
scalene triangle - all sides/angles have different lengths
*an equilateral triangle is an isosceles triangle, but not all isosceles triangles are equilateral triangles

so the answer to this question would be c)isosceles since two angles both measure 70 degrees

Answer 2

If 2 angles measure the same, then the opposite sides of these are the same. So the triangle is isosceles.

It's not scalene, because again two sides are the same. Since the third angle is 180 - 70 - 70 = 40, it's not obtuse nor right either.

Answer 3

it can not be obtuse because if you have two 70 degree angles than the third angle would have to be 40 degrees so there is not an obtuse angle (obstuse angles are greater than 90 degrees)

it can not be a right anlge because one anlge would have to be 90 degrees

It can not be scalene because all three sides would have to be different lengths and since you have two angles that are the same then two of the sides have to be the same

so the answer is Isosceles because an isoscelese triangle is a triangle with at least two sides that are equal

Answer 4

I think isosceles. but my geometry skills are rough. Because if 2 angles are the same then the opposite sides are the same.

Answer 5

It is isosceles. because the sides opposite the equal angles are equal to each other.

Answer 6

The answer is a scalene triangle

Answer 7

as two of the angles are equal it is a isosceles

Answer 8

that's an isosceles triangle.

Answer 9

c

Answer 10

c) isosceles
