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.


How do you find out how many sides a shape has using the interior angle?

To find the number of sides ( n ) of a polygon using its interior angle ( A ), you can use the formula for the interior angle of a regular polygon: ( A = \frac{(n-2) \times 180}{n} ). Rearranging this equation, you get ( n = \frac{360}{180 - A} ). By substituting the known value of the interior angle ( A ), you can calculate the number of sides ( n ) of the polygon.


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 152 sided shape have?

To find the number of diagonals in a polygon with ( n ) sides, you can use the formula: (\frac{n(n-3)}{2}). For a 152-sided shape, the calculation would be (\frac{152(152-3)}{2} = \frac{152 \times 149}{2} = 11376). Therefore, a 152-sided shape has 11,376 diagonals.
