Does exterior angle of a triangle equals the sum of the interior angles?
Actually, no. The sum of the exterior angles of a triangle is 360 degrees. The sum of the interior angles of a triangle is 180 degrees.
What is the measure of one of the exterior angles of regular pentagon?
Mathematically - A regular pentagon has interior angles and sides equal. Bisecting each interior angle and extending a line segment to the center gives you five equal angles (360o/5=72o). Using the triangle formed by two line segements and a side of the pentagon we know the sum of interior angles of each triangle equals (180o) and we know one angle is 72o. The sum the other two interior angles of each triangle equals (180o-72o=108o) which equals each interior angle of the pentagon (equal to the sum of these two angles). Thus the exterior angle of each corner of the pentagon equals (360o-108o=252o). :-)
What is the measure of each exterior angle of a triangle?
Any exterior angle of a triangle always equals the sum of the two interior opposite angles.
Why triangle is called a triangle?
triangles are called what they are because it has 3 angles "tri" is another way of saying 3 and it is made up of 3 90 degree angles in each corner The 3 angles of a Triangle when added together always equals 180 degrees.
How do you calculate the missing degree of a triangle?
The sum of all the angles in a triangle equals 180o. To find the missing angle, subtract the sum of the two known angles from 180o.ExampleTwo angles of a triangle are 35o and 62o. What is the third angle?Solution180o - (35o + 62o) =180o - 97o = 83o
Does exterior angle of a triangle equals the sum of the interior angles?
Actually, no. The sum of the exterior angles of a triangle is 360 degrees. The sum of the interior angles of a triangle is 180 degrees.
What is the value of x if a triangle has two 50 degree angles?
If you meant x to be the third interior angle, x would equal 80, because the sum of all three interior angles of a triangle equals 180. So 80+50+50=180
What is a polygon called if the sum of its interior angles equals 180 degrees?
A triangle
What is the area of a triangle if angle a equals 42 degrees angle b equals 87 degrees and angle c equals 24 degrees?
A triangle with interior angles of 42, 87 and 24 degrees doesn't exist because the angles add up to 153 degrees whereas the interior angles of any triangle always add up to 180 degrees.
What if the sum of two angles of a triangle equals 120 degrees the third angle is 60 degrees because the sum of all angles in a triangle equals 180 degrees?
Yes the 3 interior angles of any triangle always add up to 180 degrees.
Given a equals 29degree's b equals 51degree's?
Assuming a plane triangle and you are referring to interior angles c equals 100 degrees
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°

A figure has 3 sides What is the sum of its exterior angles?
360A triangle is a polygon with three sides and three angles. The sum of the interior angles of a polygon equals 180(n - 2), where n is the number of sides.180(3 - 2) = 180°Assuming all the angles in the triangle are congruent, find the measure of one interior angle.180° ÷ 3 = 60°If an interior angle equals 60°, then its corresponding exterior angle will equal 120° because the angles are supplementary (their sum is 180°).120° × 3 = 360°Therefore, the sum of the exterior angles of a triangle is 360°.study island
The measure of each angle of a triangle equals the sum of the measures of its two remote interior angles?
No. That is true only of a 90° angle.
What is the sum of the interior angles of a 38-gon?
The sum of the interior angles of an n-gon is found by the formula: (n-2)*(180) degrees. So a 38-gon would have (38-2)*(180) degree sum for its interior angles, which equals 6,480 degrees.
