they all add up to 180 degrees. so if you are given 2 of the angles then you add them together. subtract them from 180 and thats your answer
The measures of the three exterior angles would be 95, 160 and 105.
It is an equilateral triangle
If a triangle is not scalene, then the triangle does not have three angles with distinct measures.
In a triangle, the sum of the measures of the angles is 180 degrees.
The equilateral triangle.
Rotating a triangle by 50 degrees will not change the measures of its exterior angles. Exterior angles are defined based on the triangle's geometry and the positions of its vertices, which remain unchanged by rotation. Thus, regardless of the triangle's orientation, the exterior angles will retain their original measures.
A right angle triangle.
a scalene triangle has no congruent sides or measures.
It is an equilateral triangle that has 3 equal interior angles of 60 degrees
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
The 3 inside angles of any triangle add up to 180 degrees.
The sum of the internal angles of any triangle is 180 degrees. Any rectangle has four 90 degree internal angles, totalling 360 degrees.
