# Same side exterior angles?

numbers on the out side of to parallel lines and on the same as traversal.

### What is co-exterior angle?

A co-exterior angle is almost the same thing as co-interior: Two angles on the same side of the transversal (in a figure where two parallel lines are intersected by a transversal). They are supplementary angles (add up to 180º). They are exterior angles meaning they are outside of the two parallel lines (opposite of interior angles which are inside the two parallel lines).

### What are the interior and exterior angles in a regular polygon?

A polygon is a closed figure in the plane. It has an inside and an outside. The angles on the inside are the interior angles. An exterior angle is the angle between any side of the polygon and a line extended from the next side. Here is an example to help. If you draw an triangle, the angles inside it are interior angles. Then if you extend any side, the angle between that line and…

### Does a regular pentagon have acute angles?

yes. Well, actually, exterior angles are acute, but interior angles are 108. 108 is larger than ninety, so interior angles are obtuse. The exterior angle is the angle formed by an extension of one side and the adjacent side. The exterior angles of a regular pentagon would be 71. The formula for finding the measure of interior angles of a regular polygon, when 'n' is the number of side, is ((n-2)*180)/n. ((5-2)*180)/5 = (3*180)/5 =…

### How do you use the exterior angles of a triangle to find interior angle measurements?

Theorem: An measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. An exterior angle is formed by one side of a triangle and the extension of an adjacent side of the triangle.In the triangle at the right, <4 is an exterior angle. The theorem above states that if <4 is an exterior angle, its measure is equal to the sum of the…

### If a regular polygon has exterior angles that measure 60 degrees how many sides does the polygon have?

Exterior angle 60 therefore interior angle at that point 180 - 60 = 120 Figure is a hexagon (Internal angles = 12 - 4 right angles or 720 degrees) All polygons have exterior angles that sum to 360 degrees. An exterior angle of a polygon is found by "extending" one of the sides and measuring the angle between that extension and the "next" side. As the polygon in question is regular and has exterior angles…

### Uses of parallel lines cut by a transversal?

There's lots of useful things you can discover when parallel lines are cut by a transversal, most of them having to do with angle relationships. Corresponding angles are congruent, alternate interior angles are congruent, same side or consecutive interior angles are supplementary, alternate exterior angles are congruent, and vertical angles are congruent.

### How do you find angles of a parallelogram?

To find the angles of a parallelogram, you have to know at least one angle (although it could be an interior or an exterior angle). There are several facts about all parallelograms: the sum of the interior angles is 360˚ (true for all quadrilaterals) opposite angles are congruent (angles that are diagonal in parallelograms have the same measure) consecutive angles are supplementary (angles that are connected by a single side add up to 180˚) If…

### What is the sum measures of the exterior angles of a regular hexagon?

It is generally accepted to count only one vertex per side when calculating the sum of exterior angles. If this is what you mean, then for every convex polygon (all angles point away from center), the sum is always 360º. However, you can also count two vertexes per side, so the sum would then be double, or 720º.

### What are at least eight features that are common to all triangles?

They have three straight lines forming three vertices's They have three interior angles Sum of interior angles are 180 degrees Sum of exterior angles are 360 degrees They will tessellate They have no diagonals The sum of any two sides is greater than the third side Area formula the same Perimeter formula the same

### Why does polygons exterior angles equal 360 degrees?

Let's assume our polygon is a n-gon with n sides. So, there are an equal number of interior and exterior angles. We know that: 1 Exterior + 1 Interior = will give us 180º \ \ ________________\___________ Side of a trapezium using symbols. Thus, the total of the exterior angles and interior angles will be 180nº [a] As we know, the formula for the sum of interior angles is 180(n-2)º [b] Subtracting [a] from [b]…
