What is a Exterior angle of a triangle?
It is: 180-interior angle = exterior angle
What is an exterior angle for a triangle?
180 minus interior angle = exterior angle
What is an exterior angle of a triangle and how does the measure of an exterior angle relate to the interior angles?
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
A triangle with one angle measuring 90 degrees?
A triangle with one angle measuring 90˚ is a right triangleIt's a right triangle because the 90˚ angle is a right angle
What is the exterior angle in a scalene triangle?
180-the interior angle.
Reregular polygon with an exterior angle measuring 120?
An equilateral triangle
Can the exterior angle of triangle be straight angle?
When any side of triangle is extended outwards then exterior angle is formed. Sum of this exterior angle and adjacent interior angle = 180o. If exterior angle = 180o(straight angle) then interior adjacent angle is 0o which is not possible. So exterior angle can't be straight angle.
What is the relationship between interior and exterior angles in triangles?
An interior angle of a triangle is the angle between two edges, measured inside the triangle. An exterior angle is formed by extending one of the edges outside the triangle, and measuring between that extension and the adjacent original side of the triangle. The sum of the interior angle and exterior angle at any given corner is always 1800 (which is Pi radians).
Which polygon exterior angle measures 60 degrees?

How do you work out exterior angle for a triangle?
It is: 180-interior angle = exterior angle
What is an exterior angle for a triangle?
180 minus interior angle = exterior angle
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
Is it possible for some triangles to have none exterior angle obtuse angle?
Yes, a Triangle can have 3 obtuse EXTERIOR angles of measure 120° ONLY in the case of an equilateral Triangle. OTHERWISE, a Triangle always has 2 obtuse Exterior angles and 1 acute Exterior angle.
How do you find a missing exterior angle of a triangle?
At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle.
What is an exterior angle of a triangle and how does the measure of an exterior angle relate to the interior angles?
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
