Lines that pass through each other at some point
What are intersecting lines?
Triangle that has at least 2 sides the same length.
What is an isosceles triangle?

Lines that intersect to form right angles.
What are perpendicular lines?
A triangle with no sides the same length.
What is a scalene triangle?
This quadrilateral has 4 right angles and all the sides are the same length. It can also be a parallelogram, a rectangle, and a rhombus.
What is a square?
How many lines of symmetry does a scalene triangle have? Explain your answer.
None, each side of a scalene triangle is a different length. The figure can not be folded to make matching parts.

What is a right triangle?
A quadrilateral with only one pair of parallel sides.
What is a trapezoid?
Can an isosceles triangle have three lines of symmetry? Explain.

If all perpendicular lines are also intersecting lines, are all intersecting lines also perpendicular lines?
No, to be perpendicular, the lines must form right angles. All intersecting lines do not form right angles.
