How many degres are there in a triangle?

The easiest way to find out how many degrees in any shape is 180*(n-2) where n equals the number of angles in the shape. Thus, triangles have 180 degrees.


How do you find the degrees of the angles of shapes?

Use a protractor or use the formula: (n-2)*180 = sum of degrees whereas 'n' is the number of sides of the shape or polygon

What shape has the most obtuse angle?

A regular polygon of n sides (where n > 4) has n obtuse angles. Since there is no limit to the number of sides that a polygon can have, there can be no limit to the number of obtuse angles in a shape.


How do you find out the number of edges on a shape?

A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.


What is the total of the internal angles of a 25 sided shape?

The formula to find the total amount of degrees contained by a shape is (n-2) * 180, where n is the number of sides. So, 25 - 2= 23, and this times (*) 180 is 4140, so the total of the internal angles of a 25-sided shape is 4140.


How many diagonals does a shape with 5 sides have?

5(5-3)/2. That it is the formula so that shape would have 5 diagonals. n(n-3)/2 where n is the number of sides

What is the size of an interior angle on a regular 15-sided shape?

156 degrees Sum of interior angles of a polygon=180(n-2), where n is the number of sides. To find one interior angle's measure, divide by the total number of angles, which is also the total number of sides.


What are multiples of number and how do you find them?

You find multiples of a number by multiplying that number by successive counting numbers. Let N equal the number. The first multiple is always the original number (N x 1) The rest will be N x 2, N x 3, N x 4 and so on.
