When two lines meet it is usual to refer to the angle between them by the smaller of the two angles they form. Both angles always add up to 360..... the usual way of defining an angle is to name the lines that form it, and to do so in a clockwise manner. Looking at the four main compass points (N, E, S and W) and naming the centre as C..... the angle between North and East would be referred to as NCE..... this angle measures 90 degrees. The exterior angle is ECN and is 270 degrees. Usually exterior angles are only referred to when the interior angle is part of an enclosed figure, such as a triangle or other polygon.

How do you work out exterior angle for a triangle?
It is: 180-interior angle = 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 The measurement of an exterior angle of a triangle is equal to the sum of?
Interior angle+exterior angle = 180 degrees
Which of these two regular polygons has the largest exterior angle heptagon or triangle .?
It is the regular equilateral triangle whose each exterior angle is 120 degrees
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.
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
What is an exterior angle for a triangle?
180 minus interior angle = exterior angle
How do you work out exterior angle for a triangle?
It is: 180-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
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.
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 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
Exterior angle of a triangle?
Exterior Angle Theorem Exterior angle of a triangle An exterior angle of a triangle is the angle formed by a side of the triangle and the extension of an adjacent side. In other words, it is the angle that is formed when you extend one of the sides of the triangle to create a new line, and then measure the angle between that new line and the adjacent side of the original triangle. Each triangle has three exterior angles, one at each vertex of the triangle. The measure of each exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to it. This is known as the Exterior Angle Theorem. For example, in the triangle below, the exterior angle at vertex C is equal to the sum of the measures of angles A and B So, angle ACB (the exterior angle at vertex C) is equal to the sum of angles A and B.

Is an exterior angle of a triangle always acute?
No :) Because one angle of the triangle is always acute and so the exterior has to be obtuse.
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.
What is The measurement of an exterior angle of a triangle is equal to the sum of?
Interior angle+exterior angle = 180 degrees
