Let the angles be a, b and c
There are 180 degrees in a triangle:
180-(a+b) = c
180-(a+c) = b
180-(b+c) = a

What is an exterior angle of a triangle?
It is: 180-interior angle = exterior angle
The sum of the measures of two interior angles of a triangle is 261 What is the measure of the third exterior angle?
That's not possible.Two interior angles of a triangle can't add up to 261°, because all three of the interior anglesin any triangle always add up to 180°.
What type of Triangle has two 35 degree angles?
Since the triangle has two identical angles, it will be an isosceles triangle. Also the third angle equals 110°, so it is an obtuse triangle, because 110° is greater than a right angle (90°). The sum of all interior angles in a triangle is 180°, so we know two of the angles are 35° and 35°, so the third angle is 180° - 35°- 35° = 110°
What is the Exterior Angle Theorem for a Triangle?
An exterior angle of a triangle is equal in measure to the sum of the other two interior angles.
In triangle DCF if angle ADF is the exterior angle the remote interior angles are?
angle dcf and angle dfc
What is the intereor angle of a triangle?
An interior angle is any angle on the interior of the triangle.
If a triangle has interior angle measure of 32 and 75 what is the measure of the third angle?
The interior angles of a 2-D triangle will always add up to 180 degrees. To determine the measure of the third angle: 180 - (32 + 75) = 73 degrees
What is a triangle with a 90 degree interior angle called?
A triangle with a 90o interior angle is called a 'right' triangle. BTW, any triangle can have only one 90o interior angle
What is the interior of an angle?
interior is the inside of a triangle but is connected to the triangle.
What has large interior angle a triangle or heptagon?
A heptagon. It can have a reflex interior angle, a triangle cannot.
How do you find the third interior angle of a triangle?
Add the first two angles together and subtract the total from 180 to find the 3rd angle
Which has a larger interior angle heptapon or triangle?
Either could have a larger interior angle. If they were regular, then the interior angle of a triangle would be 60 degrees whereas that of a heptagon would be 128.57 degrees. The REGULAR heptagon would have a larger interior angle than a REGULAR triangle.
Can a triangle have to right angles if yes what would be the size of the third angle?
A right angle triangle can only have 1 right angle of 90 degrees and its 3 interior angles add up to 180 degrees
Exterior angle property of a triangle?
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
What is the definition of the remote interior angle of a triangle?
Remote interior angles are the two angles of a triangle that are not adjacent to the exterior angle which is drawn by extending one of the sides. So when you draw out your triangle, the remote interior angles are the two angles that are the furthest away from your exerior angle.
What is an exterior angle of a triangle?
It is: 180-interior angle = exterior angle
What is a Exterior angle of a triangle?
It is: 180-interior angle = exterior angle
