If the exterior angle of a regular polygon equals 90 degrees then the polygon is a?
Square, or a rectangle. * * * * * Since it is a REGULAR polygon, it cannot be a rectangle. So the only answer is a square.
How do you work out exterior angle for a triangle?
It is: 180-interior angle = exterior angle
Is an exterior angle of a quadrilateral always sometimes or never 90 degrees?
An exterior angle of a quadrilateral is sometimes 90 degrees. While it can take on various values depending on the shape and angles of the quadrilateral, there are specific configurations, such as a rectangle, where an exterior angle is exactly 90 degrees. However, in general cases, it can also be acute or obtuse, so it is not always 90 degrees.
What is the exterior angle measurement of a 4-gon?
((4 x 360) - 360) = 3 x 360 = 1080o so if it's regular, eg a rectangle, each angle is 270o
What is the exterior angle the interior angle and the angle at the center of a regular polygon with 15 sides?
Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.
What is the measure of each exterior angle of rectangle?
270
What is an exterior angle?
Think outside the box. Draw a rectangle. Each corner (interior angle) is 90 degrees. The four exterior angles are the other sides of the corners.
If the exterior angle of a regular polygon equals 90 degrees then the polygon is a?
Square, or a rectangle. * * * * * Since it is a REGULAR polygon, it cannot be a rectangle. So the only answer is a square.
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
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
How do you find exterior angle?
the hypotenuse is the exterior angle
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 exterior angle for a octagon?
180 minus interior angle = exterior angle
What is the measure of a exterior of an angle of a tringle?
180-interior angle = exterior angle
What is an exterior angle for a triangle?
180 minus interior angle = exterior angle
How is an exterior angle of a polygon formed?
180 - interior angle = exterior angle
