You can use SAS. This means you are given two lengths of lines and one angle. You can then work out the area
No, you can't have two lines that are both parallel and perpendicular.
An isosceles right triangle is a 45Â° 45Â° 90Â° triangle. If you know how to construct a right angle (two lines that are perpendicular), then just take a compass, with the point on the intersection of the perpendicular lines, and mark the same distance on each of the perpendicular lines, then use a straight edge to connect those two points. Or, if you have a square, you can connect two of opposite corners with a diagonal and you will have 2 triangles, both of them isosceles right triangles.
It has both
A heptagon can have all 7 lines that are perpendicular to one or both its neighbours.
As far as we know, two lines can be perpendicular, or they can be parallel, but they can't be both.
Perpendicular lines are specific kinds of intersecting lines. They both cross paths. Intersecting lines can cross paths in any way, but perpendicular lines have to cross at right angles.
They both cross paths. Intersecting lines can cross paths in any ways, but perpendicular lines have to cross at 90 degrees.
area = 1/2 base * perpendicular height you can't find both the base and the height if you only know the area
No, two lines perpendicular to each other are wriiten as two separate equations. Both are linear.
the parallel lines never intersect each other but they both intersect the line they are perpendicular to
Since two parallel lines never intersect, they cannot be perpendicular to each other because perpendicular lines intersect and form angles of 90⁰.
