Do The interior angles of both a regular and irregular pentagon have a sum of 1080 degrees?
Yes. In the regular polygon, the angles are all equal parts of the 1,080 . In the irregular one, there are bigger and smaller interior angles, but they still add up to the same total.
How many interior angles does a polygon have?
There are as many interior and exterior angles as there are sides (the line segments that make up the polygon. The sum of each pair of exterior angle and interior angle is 180 degrees, i.e. they are supplementary. For concave polygons, there will be at least one "negative" exterior angle paired with an interior angle of greater than 180 degrees - the total of the angles is still 180 degrees.
Can a pair of straight angles can also be adjacent angles?
Yes, a pair of straight angles can be adjacent angles. Adjacent angles are defined as angles that share a common vertex and a common side but do not overlap. If two straight angles share a common vertex and one side, they can be positioned next to each other, making them adjacent while still each measuring 180 degrees.
How many total degrees are there among all angles of a hexagon?
720° Each angle for a N-sided regular polygon can be found by:Interior Angle = 180° - (360°/N) ; For N=6 this is 120°. Then for the total of all angles, just multiply by 6. Note that the total of all angles will still be 720°, even for a non regular hexagon. So general formula for total of all interior angles:(Sum of interior angles) = N*180° - 360°
How many acute angles and obtuse angles does a irregular hexagon have?
An irregular hexagon can have a varying number of acute and obtuse angles, as long as the sum of its interior angles equals 720 degrees. In general, an irregular hexagon can have anywhere from 0 to 6 acute angles and from 0 to 6 obtuse angles, depending on the specific shape and arrangement of its angles. The key is that the total must still conform to the 720-degree requirement.
Do The interior angles of both a regular and irregular pentagon have a sum of 1080 degrees?
Yes. In the regular polygon, the angles are all equal parts of the 1,080 . In the irregular one, there are bigger and smaller interior angles, but they still add up to the same total.
Would the angles of a triangle stay the same if the triangle shrinked?
Yes and its 3 interior angles would still add up to 180 degrees
How many interior angles does a polygon have?
There are as many interior and exterior angles as there are sides (the line segments that make up the polygon. The sum of each pair of exterior angle and interior angle is 180 degrees, i.e. they are supplementary. For concave polygons, there will be at least one "negative" exterior angle paired with an interior angle of greater than 180 degrees - the total of the angles is still 180 degrees.
What are the properties of an acute triangle?
All the interior angles are less than 90 degrees ( or a right angle ) Sum of all the angles is still 180 degrees. kapm
Can a pair of straight angles can also be adjacent angles?
Yes, a pair of straight angles can be adjacent angles. Adjacent angles are defined as angles that share a common vertex and a common side but do not overlap. If two straight angles share a common vertex and one side, they can be positioned next to each other, making them adjacent while still each measuring 180 degrees.
What is the old math tool D shaped ruler?
It sounds like you are thinking of a protractor. We still use it a lot today, especially in architecture and design. The protractor is a semi-circular measuring instrument used for measuring angles.

How will humans survive without measuring tools?
We humans do still have measuring tools, so I am not sure why this question comes up, but if for some reason we were to lose all of our measuring tools, then we would just have to make estimates. Or create new tools.
Why does the exterior angles of an E shaped polygon total 360 degrees when it has 8 interior right angles and 4 interior reflex angles?
The exterior angles of any polygon total 360 degrees and the E shaped polygon is a 12 sided shape that has a total of 360 degrees of exterior angles and a total of 1800 degrees of interior angles. If you were to walk around an enlarged E shaped polygon in a clockwise direction you would have to make 8 right angle turns clockwise and 4 right angle turns anti-clockwise from start to finish. So: (8-4)*90 = 360 degrees in a clockwise direction Or to put it another way if you were to enscribe a circle and then enscribed 4 arcs of 90 degrees in reverse on the same circle you would still end up with a complete circle of 360 degrees. Interior angles: 8*90+4*270 = 1800 degrees
What characteristics help you classifly a quadrilateral as a parallelogram and not a rectangle?
A rectangle has four interior angles that are exactly 90 degrees. A parallelogram can have two opposite angles larger than 90 and the other two, smaller than 90 degrees but still add up to 360 degrees.
If all polygons are supposed to have 360 exterior angles then why does a T shaped polygon have at least 540 if not 720 exterior angles when it has 6 interior right angles and 2 interior reflex angles?
A T shaped polygon is an octagon that has 360 degrees of exterior angles and 1080 degrees of interior angles. If you were to walk around a large T shaped polygon in a clockwise direction you would have to make 6 right angle turns clockwise and 2 right angle turns anti-clockwise from start to finish. So: (6-2)*90 = 360 degrees in a clockwise direction Or to put it another way, if you were to travel for 540 miles and then travelled back on the same route for 180 miles and then stopped altogether. Although you had travelled a distance of 720 miles you would still be 360 miles from your starting point. Interior angles of the T shaped polygon: 90+90+90+90+90+90+270+270 =1080 degrees.
