What is Right Angled triangle?
A right-angled triangle is one which has, as one of the angles, an angle of exactly 90 degrees.
Do all of the angles on a right angled triangle have to be the same?
No a right angled triangle consists of two acute angles and one right angle
How can you calculate the length of the hypotenuse of a right angle triangle?
By using the formula a2+b2=c2, where a is one side of the right-angled triangle and b is the other side of the right angle triangle. C stands for the hypotenuse of the right-angled triangle. Note: this formula only works for RIGHT-ANGLED TRIANGLES!!!
How many degrees in a right angled triangle?
I depends what posision the triangle is in.
Is right angled triangle regular or irregular?
A regular triangle would have all angles equal, each being 60o. Thus a right angled triangle is an "irregular" triangle in that one of its angles is 90o which is not 60o.
Does a right angled triangle have rotational symmetry?
No.
What is the order of rotational symmetry of a right angled triangle?
None.
What rotational symmetry does a right-angled triangle have?
I think none. In fact the only triangle that I believe has any rotational symmetry is an equilateral triangle.
How many lines of rotational symmetry in a right angled triangle?
3
Does a right triangle have lines of symmetry Rotational symmetry?
Not necessarily, except rotational symmetry of order 1.
What figure does not have rotational symmetry?
a right triangle
Does a right angled triangle have a line of symmetry?
yes * * * * * Usually, no. Only isosceles right angled triangles have a line of symmetry.
Does a right triangle have rotational symmetry?
The modern answer is that if the shape only fits once onto the original when rotated 360o it has no rotational symmetry. A right triangle only fits once when rotated 360o so it has no rotational symmetry.
What is the name of the triangle with no lines of symmetry and no right angles?
A scalene triangle that is not right angled.
Lines of symmetry in a right angled triangle?
None normally but if it is a right angle isosceles triangle it will have 1 line of symmetry
How much lines of symmetry does a right angled triangle have?
it has only one line of symmetry.
What is a triangle with 1 axis of symmetry?
This could be either an isosceles triangle or a right angled triangle.
