55
Improved Answer:-
It is: 180-54-54 = 72 degrees
If two angles of a triangle each measure 55 what is the measure of the third angle?
180- total of the first two angles= 3rd angle
The base angles will have equal angles of 50 degrees
Each angle is 60 degrees
...a right triangle.
16.5 degrees
If two angles of a triangle each measure 55 what is the measure of the third angle?
Two angles of a triangle add up to 65°. What is the measure of the third angle?
180- total of the first two angles= 3rd angle
The missing angle measure is 100 degrees.
They are all 60 degrees.
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
the sum of the angles of a plane triangle is always 180° In an equilateral triangle, each of the angles is = Therefore, the angles of an equilateral triangle are 60°
measure of exterior angle of triangle is equal to sum of interior angles. for eg. In triangle ABC, angle C is exterior angle angle A and angle B are interior angles so, C=A+B
A Triangle which do not have a right angle.
It is a straight line which divides an interior angle of the triangle into two angles of equal measure.
If you mean angles then it is a right angle triangle or an isosceles right angle triangle
