How many right-angled triangles have lengths with whole numbers?
An infinite number. Working only with the 3,4,5 triangle, you get: (*2) 6,8,10 or (*3) 9,12,15 or (*4) 12,16,20 or (*5) 15,20,25 etc for ever. And, apart from that, there are an infinite number of starting triplets (5,12,13) is the next smallest one.
What kind of triangles are there?
There are many kind of triangles. These are the following: Acute, Right, and Obtuse are actual angles. Scalene, Isosceles, and Equilateral are all actual triangles. But, you can have any triangle with any angle. Like a scalene triangle with a Right angle, or an Isosceles triangle with an Obtuse angle.Acute is a triangle with an angle less than 90 degrees. So it is smaller than a Right triangle. To make and Acute triangle, you need at least two Acute angles.Right triangle have at least on right angle. Right angles are angles that re exactly 90 degrees. If you put a cube right where the angle went, both sides would be perfectly straight.Obtuse triangles are triangles with at least one Obtuse angles. They are always bigger than 90 degrees. They are larger than a Right triangle. If you spread your legs apart, you would have an Obtuse angle.Scalene triangles are triangles with all of the sides different lengths. Each side is either longer or shorter, they are never the same.Isosceles triangles are triangles with two sides the same lengths. The other side is either longer or shorter.Equilateral triangles are triangles with ever side the same exact length. They all are exactly the same. If one is different, it's not an Equilateral triangle.
The sum of the interior angle measures of an octagon?
To find interior angle measurements, you must divide the shape into triangles by drawing diagonal lines. The diagonal lines draw triangles, and the interior angle measure of triangles are always 180 degrees. The sum of interior angles of an octagon is 1080 degrees. How ever many triangles you have, multiply it by 180. See octagons in the link for more help,
What traingle has a reflex angle?
No triangle can ever have a reflex angle inside it.
Do a hexagon have 2 right angles?
A hexagon has no right angles what-so-ever.
