What angles do a scalene triangle have?
-- A scalene triangle has three interior angles and three exterior angles. -- The sum of the interior angles is 180 degrees, and no two of them are equal. -- The sum of the exterior angles is also 180 degrees, and no two of them are equal. -- The sum of each interior angle and its adjacent exterior angle is 180 degrees.
What is sum of the interior angles of a polygon with three sides?
the sum of the interior angles of a 3 sided polygon is = 180 degrees. the sum of the interior angles of any polygon is given by 540/n. in this case n is = 3
What is the sum of the interior angles of a three-sided polygon?
The 3 interior angles of a 3 sided polygon which is a triangle add up to 180 degrees.
How many sides does a polygon have with interior angles of 60?
Three: it is an equilateral triangle.
What are the angles on the outside of triangles?
The Exterior angles are named as 'REFLEX' angles. At any one angular point, the sum of the Interior angle and the Exterior angle equals 360 degrees. There being three angles in a triangle, then the sum of all the angles is 3 x 360 = 1080 degrees. Since the sum of the three interior angles is 180 degrees., then the sum of the exterior (reflex) angles is 1080 - 180 = 900 degrees.
Which regular polygon's interior angles is three times that of its exterior angles?
octagon interior=135 exterior=45

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
What is the sum of the interior angles of a three-sided polygon?
The 3 interior angles of a 3 sided polygon which is a triangle add up to 180 degrees.
How many interior angles does an irregular polygon have?
Three or more.
The measures of the three interior angles of a triangle are 85 20 and 75 Determine the measures of the three exterior angles?
The measures of the three exterior angles would be 95, 160 and 105.

How many sides in a polygon whose interior angle is 174?
It could be three. It could be a triangle with angles of 174, 3 and 3 degrees. If it is a REGULAR polygon, though, there is a more specific answer. Interior angle = 174 deg implies exterior angle = 6 deg. Sum of ext angles = 360 deg so there must be 360/6 = 60 sides to the polygon.
Which polygon has three interior angles each measuring 60 degrees?
An equilateral triangle.
What are the characteristics of polygons?
A polygon is any plane figure bounded only by straight lines. A triangle is therefore a polygon with three sides and a pentagon is a polygon with five sides. A convex polygon has no interior angle greater than 180° . A re-entrant polygon has at least one interior angle greater than 180° . A regular polygon has all its sides and angles equal. The sum of the interior angles of a polygon is 2n - 4 right angles (n is the number of sides). The sum of the exterior angles of a convex polygon is 360° .
