An isosceles triangle must have at least two equal sides, and two equal angles. The sum of all three angles is 180 degrees.
None but 2 of its 3 sides are equal in length and it has one line of symmetry
2
180
One
The 2 diagonals in an isosceles trapezoid are of equal lengths
because an isosceles triangle or any kind of triangle is 180 degrees.
Triangles have 0 diagonals.
A triangle has no diagonals
Not for all trap. Only for an isosceles trapezoid. Well, for an Isosceles trapezoid, it could be any of the two diagonals! In order to have an isosceles trapezoid with the diagonals equal, the isosceles part MUST be precise and specific.
0 they have no diagonals
You can't because triangles do not have diagonals but an isosceles triangle has 2 equal sides
If you mean an isosceles triangle then no because all triangles have no diagonals
There are no 'diagonals' in a triangle. Each vertex is connected to both of the other vertices, by the sides.
No. An isosceles trapezium (isosceles triangle with its apex removed) would have congruent diagonals but it is not a parallelogram.
Yes, they are because it would just be a scalene triangle if they weren't.
Well an iscosceles triangle means that two of the sides are the same, so I would think that both of the diagonals would be congruent.
A trapezium has two diagonals.
It is an isosceles triangle with a right angle between the sides of equal length. Also the equal angles are 45o. * * * * * Take a square, draw one of its diagonals. The shape that is on one side of that diagonal is a right isosceles triangle.
there are three angles on an isosceles triangle
a triangle has three diagonals as well as three sides
No. An isosceles right triangle is a special case. There are many right triangles which are not isosceles.
