What are the total angles in a square?
each angle is 90 degrees and because there are 4 the total sum of a squares angles is 360 degrees. You can find the sum of any shapes angles with the formula: S=(n-2)x180 Where S= the Sum of the angles and n= the number of sides the shape has
What shapes have 2 equal angles?
a right angled triangle.
Why is it that if a shape is congruent its similar?
Congruency means that the given 2 figures are exactly same in shape and size. Thus all corresponding angles will also be the same.Similarity of shapes means that the 2 given shapes are same in shape but the measures of corresponding sides may not be the same. Since the shapes are the same, the corresponding angles are also same.If 2 shapes are congruent, they have equal corresponding angles. The equal angles satisfy the condition for the shapes being similar. Hence congruent shapes are similar as well.
How many degrees are in a 15 sided shapes?
N-2 X 180= polygon total angles. Where N equals 15. That is (15-2)X180=2340 degrees.
What shapes have acute angles?
A polygon, that is, a plane area bounded by any number (>2) of straight lines can have acute angles.
