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.
Yes, because you can notice that the right angled triangle has one right angle, so its only 1 perpendicular line. Hope this helped :D
Right triangles can have only one line of symmetry. Only right triangles with two 45 degree angles can have a line 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.
The area of a 12cm by 5cm right-angled triangle is: 42 cm2
A scalene triangle that is not right angled.
it has only one line of symmetry.
None normally but if it is a right angle isosceles triangle it will have 1 line of symmetry
