Two of the three lines in a right triangle are perpendicular. Perpendicular lines meet at a 90 degree angle (also called a right angle). All right angle triangles have one right angle.

It could be a right triangle if it has a right angle (90 degrees). If it does not have a right angle, then it is an acute triangle.
A right angle triangle
A Right Triangle or sometimes called a Right-angled Triangle has one angle = 90 degrees
is a right angle that intersects and 3 lines of symmetry
None normally but if it is a right angle isosceles triangle it will have 1 line of symmetry
A right scalene triangle
The number of lines of symmetry of a triangle depends upon the kind of triangle it is:A scalene triangle with no side lengths equal has no lines of symmetry;An isosceles triangle with two sides equal has 1 line of symmetry that bisects the angle between the two equal sides;An equilateral triangle with all three sides equal has three lines of symmetry - the three lines are the bisectors of the three angles.A right triangle is a triangle where one angle is 90°. A right triangle is either a scalene triangle with no lines of symmetry or an isosceles triangle (where the legs are of equal length) with one line of symmetry which bisects the 90° angle.No triangle can have exactly 2 lines of symmetry.
1 its from the "right angle point" on a diagonal to the center of the longest line.None normally but if it's an isosceles right angle triangle it will have 1 line of symmetry.
It depends. If it is a right isosceles triangle, it has one axis of symmetry (the line which would bisect the right angle). A right scalene triangle has no axis of symmetry.
An equilateral triangle has three lines of symmetry. Pick a corner, and draw a line from there to the center of the opposite side of the triangle. That is one of the lines of symmetry. You can get the other two lines by doing this to the other two corners. An isosceles triangle only has one line of symmetry and a scalene triangle has none.
A right angle has one line of symmetry.
0 lines of symmetry
a triangle has 0 lines of symmetry.
YES!!! An equilateral triangle has three lines of symmetry. They are drawn from any one corner to the opposite base. They should all intersect at the centre of the triangle. By comparison, an Isosceles triangle has only one line of symmetry. From the one unequal angle to the opposite side. Right angled, and scalene triangles do not have lines of symmetry.
No triangle has two lines of symmetry. A right triangle and an Isoscoles triange each have one line of symmetry, and an equilateral triangle has three.
