Are the diagonals of an isosceles triangle perpendicular?
There are no 'diagonals' in a triangle. Each vertex is connected to both of the other vertices, by the sides.
How many diagonals does a isosceles trapezium have?
A trapezium has two diagonals.
How many pairs of perpendicular lines does an isosceles triangle have?
There can be only one pair of perpendicular lines in an isosceles triangle when it is a right angled isosceles triangle. A non right angled isosceles triangle has no pairs of perpendicular lines.
How many lines of symmetry are there in a triangle?
In an equilateral triangle: 3 In an isosceles triangle: 1 In a scalene triangle: 0
Does an isosceles trapezoid have diagonals that bisect each other?
An isosceles trapezoid, or any trapezoid, does not have diagonals that bisect each other.
How do you prove the diagonals of an isosceles triangle congruent?
You can't because triangles do not have diagonals but an isosceles triangle has 2 equal sides
Are the diagonals of an isosceles always congruent?
If you mean an isosceles triangle then no because all triangles have no diagonals
Are the diagonals of an isosceles triangle perpendicular?
There are no 'diagonals' in a triangle. Each vertex is connected to both of the other vertices, by the sides.
Are all quadrilaterals with congruent diagonals parallelpgram?
No. An isosceles trapezium (isosceles triangle with its apex removed) would have congruent diagonals but it is not a parallelogram.
Are the diagonals congruent in an isosceles triangle?
Yes, they are because it would just be a scalene triangle if they weren't.
Are the diagonals of an isosceles triangle congruent?
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.
How many diagonals does a isosceles trapezium have?
A trapezium has two diagonals.
What does a a right isosceles triangle look like?
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.
How many angle does a isosceles triangle?
there are three angles on an isosceles triangle
How many diagonals does a triangle have?
a triangle has three diagonals as well as three sides
Is a right triangle always an isosceles triangle?
No. An isosceles right triangle is a special case. There are many right triangles which are not isosceles.
What is true about the diagonals in an isosceles trapezoid?
The 2 diagonals in an isosceles trapezoid are of equal lengths
