All right angles will be equal as they are all 90O. Shapes that have 4 right angles will be rectangles (which include squares).
a right angled triangle.
A rhombus has 4 equal sides but no right angles
That's three different shapes: a rectangle, a rhombus and a trapezoid respectively.
The lengths of the 4 sides of a rhombus are equal but a rhombus has no right angles
No. For example a parallelogram does not have any right angles. The internal angles of all four sided shapes will always equal 360 degrees, but do not necessarily have to include right angles.
wich shaps have right angles
45 degrees. they have to be the same angle, because they are opposite equal lengths, and when added together they must equal 90, so as to make the total of the angles 180.
Yes, those polygons which have angles of 90 degrees and equal side lengths are called squares; those with uneven side lengths are called rectangles.
a rectangle (that is NOT a square) has 4 right angles and consecutive sides of unequal lengths.
No.Equilateral triangles must have equal angles (all 60 degrees) and equal length sides; there are also:Isosceles triangles which have two equal angles and two equal sides;Scalene triangles which have all three sides, and hence all three angles, of different lengths;Right angled triangles (which can have all sides of different lengths, or two sides of equal length) have (as the name suggests) one right angle. This means Pythagoras and the trigonometric ratios can be used on its side lengths.
