∙ 12y agoWhen finding the angles, the length of the sides is irrelevant in this case.
Let the triangle be ABC with ∠A the vertex and BC the base; the real question is whether you have the isosceles triangle "drawn" and labelled with the equal sides:
vertex_angle = 180o - 2 x 70o
= 40o
vertex_angle = (180o - 70o) ÷ 2
= 55o
Isosceles triangles are often drawn in the first case, but it is not necessarily so!

∙ 12y agoNo. An isosceles right triangle has the measures of 90, 45, and 45. Isosceles means that two sides are congruent. Hope this helps :)
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
Isosceles right angled triangle, as the remaining angle must be 90o.
yes
45 degrees.

A triangle with two congruent sides is isosceles. A triangle with an angle of 104 degrees is obtuse. So you would have an obtuse isosceles triangle.
It is an isosceles triangle and its other two angles each measures 35 degrees
Isosceles right angled triangle, as the remaining angle must be 90o.
Isosceles Triangle Isosceles TriangleIsosceles triangles have at least 2 congruent sides, and equilateral triangles have all 3 sides equal. A scalene triangle has no congruent sides or angles. All triangles have 180 degrees total.An equilateral triangle has three congruent sides and an isosceles triangle has two congruent sides.

It is possible if neither of the angles in the triangle measures to 60 degrees
Yes. Only if the other two angles of the right triangle are congruent and each equal 45 degrees. Then using the isosceles triangle theorem, you know that the two sides opposite the angles are congruent.
yes
A scalene triangle. In a scalene triangle, there are no congruent sides or angles. In an isosceles triangle, at least two congruent sides and angles. In an equilateral triangle, all three sides and angles are congruent, with angles that always measure sixty degrees. Note: an equilateral triangle also classifies as an isosceles triangle, as it meets the definition of an isosceles triangle mentioned above.
62 degrees
