to find the entire angle sum of a pentagon you would have to subtract 2 from 5, because 5 is the number of sides. You then take 3 and multiply it by 180. if it is a regular pentagon you just simply divide 540 by 5 (the number of angles) and that is the measure of each angle in the pentagon. If it isn't a regular pentagon you subtract the 3 angle measures you know from 540 and then with the remaining number you use thereoms and postulates and stuff to find the angle measures
What else can I help you with?
How many right angles does it have in a pentagon?
A pentagon can have:none (regular or irregular pentagon)one, two or three right angles (irregular pentagon).
What is the measure of the first three angles in the pentagon?
That will vary, depending on the pentagon.
How many right angles in a pentagon?
A pentagon can have anywhere from none to three right angles. For a pentagon to have any right angles however, it has to be uneven, because the sum of all interior angles of a pentagon always equals 540 degrees.
What do a pentagon and a triangle have in common?
A pentagon and a triangle are both polygons. There are three triangles in a pentagon. Both a triangle and a pentagon have exterior angles that add up to 360 degrees
What shape has more sides than a triangle or rectangle but less angles than hexagon?
A shape that has more sides than a triangle or rectangle but fewer angles than a hexagon is a pentagon. A pentagon has five sides and five angles, which fits the criteria, as a triangle has three sides and angles, a rectangle has four sides and angles, and a hexagon has six sides and angles.

Can a pentagon have three right angles and if not or if so explain why?
Yes it can. Imagine a square with the corner cut off. The remaining shape is a pentagon with three right angles.
What is the interior angle of a pentagon?
The measurement of an interior angle of a pentagon depends on whether the pentagon is a "regular pentagon". The sum of the measures of the interior angles of any polygon can be calculated using the formula (n-2)180, where n = the number of sides. If the pentagon is a regular pentagon, then all of the interior angles are congruent (i.e. : 144 degrees). Interior angle is the inside angle of any angular object. A triangle for instance has three outside angles and three interior angles, the angles of the points from the inside.
What do a pentagon and a triangle have in common?
A pentagon and a triangle are both polygons. There are three triangles in a pentagon. Both a triangle and a pentagon have exterior angles that add up to 360 degrees
What is a five sided shape with three right angles called?
a Pentagon is five sided and CAN have 3 right angles.
What shape has Five sides and one right angle?
Five side is always a pentagon, but there's no pentagon that always has exactly one right angle. A regular pentagon has no right angles. An irregular pentagon can have one, two, or three right angles, or none.
Is there a pentagon with a right angle?
Strictly speaking a pentagon is a plane figure with five straight sides and five angles, so yes, a pentagon can have one - or more - right angles. Imagine a rectangle with one of the corners cut off - that would have five sides and three right angles. .......... ............. ................ .................. .................. .................. ..................
When a pentagon has two angles that measure 145 and 74 and the other angles are all congruent what are their measurements?
The measurement for the other three angles are 107 degrees.
Does a pentagon have 5 right angles or 3?
Pentagons in normal (Euclidean) geometry can have at most three right angles, and the other two will be obtuse.However, in hyperbolic geometry, it is possible to construct a pentagon with 5 right angles, which is called a rectapentagon.
What are the sizes of angles in a pentgonal pyramid?
A regular pentagonal pyramid is composed of five equilateral triangles and one regular pentagon. Each equilateral triangle has three angles of 60 degrees each. The regular pentagon has five internal angles of 108 degrees each.
