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.
How many parallel lines does a riht angled triangle have?
There are no parallel sides in a right angle triangle
Classify the triangle by its angles?
An acute angled triangle has all its angles less than 90°.A right angled triangle has one of its angles equal to 90°.An obtuse angled triangle has one angle greater than 90°.A scalene triangle has all three sides of different lengths.An isosceles triangle has two sides and two angles equal.An equilateral triangle has all its sides and angles equal.
Is 7 8 12 a right triangle?
7, 8 & 12 are the sides of the triangle.And, for a right angled triangle the Pythagoras theorem is always applicable!Pythagoras theorem states that for a right angled triangle:(Longest Side)2 = (Side-1)2 + (Side-2)2(Longest side is called as the hypotenuse).So, using data in the question:If its a right angled triangle--->122 = 72 + 82i.e. 144 = 49 + 64 => 144 = 113, which is clearly not true!Hence, the triangle with the given sides is not a right triangle.
What is a triangle with one 90 degree angle?
A right triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.
