We have no way to know that, from the information given in the question.
All we know, if the triangle is isosceles, is that two of the angles are equal,
and that all three angles sum to 180 degrees.
90° 45° 45°
51 degees
(180-112)/2=34
Its 2 equal base angles will each measure 65 degrees
Yes normally, unless it is a right angle isosceles triangle which will have angles of 90, 45 and 45 degrees.
90° 45° 45°
51 degees
70
55 degrees
(180 - 78) / 2...
These are the degrees of each angle. It is a right triangle, and it also is an isosceles triangle.
(180-112)/2=34
Its 2 equal base angles will each measure 65 degrees
Yes normally, unless it is a right angle isosceles triangle which will have angles of 90, 45 and 45 degrees.
Each base angle is 62.5 degrees
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
If it is an isosceles triangle then the base angles must be equal angles of 69 degrees because there are 180 degrees in a triangle and 42+69+69 = 180 degrees
