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!!!
Does a right triangle have two equal sides?
A right triangle can NEVER have two equal sides (in euclidean space). Triangles with two equal sides are known as isosceles triangles.
Which triangles have a right angle?
Right angled triangles!
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.
Can a right-angled triangle be isosceles?
Yes, it is called a right isosceles triangle. The the longest side is across from the right angles as usual, and the other two sides are of equal distance
Does a right-angled triangle have any equal sides?
A right-angled triangle can have equal sides, but does not have to. A right-angled triangle with two equal sides CANNOT be an equilateral triangle. A right-angled triangle cannot be an equilateral triangle.Divide a square along the diagonal, and you are left with two right-angled triangles with two sides of equal length.
Does a right angled triangle have all equal sides?
right angled triangle does not have all equal sides
Does right angled triangle has 90 degrees?
All triangles have 180o. A right-angled triangle has one right angle. A right angle is 90o.
What triangles are formed when you draw a line down the middle of an equilateral triangle?
an icoceles triangle or a scalene triangle Actually you would get two right angled triangles. Isosceles triangles have two sides which are equal in length. A scalene triangle has all sides a different length and no right angles.
Does a right angled triangle have vertices?
Vertices are the main property of triangles. No vertices, no triangle.
Are scalene triangles all obtuse?
No, a scalene triangle is simply a triangle where all angles are not equal and all side lengths are not equal, therefore they can or cannot be obtuse.
What are the two general kinds of triangles?
might be an equilateral triangle. isosceles triangle or a right angled triangle :)
Does a right angled triangle have a line of symmetry?
yes * * * * * Usually, no. Only isosceles right angled triangles have a line of symmetry.
What is Circumradius of a right angled triangle?
The circumradius of a right angled triangle would be equal to half the length of its hypotenuse.
How many degrees does a Traiangle have?
All angle in a triangle add up to 180o. In an equilateral triangle, each of the three angles is equal to 60o; in isosceles triangles, two angles are equal; in scalene triangles, none are the same; in right-angled triangles, one of them must be 90o.
Can trigonometry be applied only in right angled triangles?
No. It can be used on any triangle.
What congruent shape can 2 right-angled triangles make?
Isosceles triangle
