One way would be to draw a square and then draw the diagonal of the square. You now have two isosceles triangles.
Another way would be to draw two line segments that intersect at a point. Take a compass and put the point at the intersection and set some arbitrary length to draw an arc. Now draw the arc between the two line segments to "connect" them. Then use a straight edge to draw another line segment between the points where the arc cuts the line segments, thus creating a triangle. The compass has marked off equal lengths along the line segments, so those sides of the triangle are equal. An isosceles triangle has two equal sides. As an extra point, an equilateral triangle is isosceles, but it is a special case of an isosceles triangle.
The later construction method is pretty straight forward (less involved) than the first, but both are 100% correct. And both methods can be accomplished using the classic "compass and straight edge method" from the days of the ancients!
You cannot. An isosceles triangle cannot be scalene and a scalene triangle cannot be isosceles. So an isosceles scalene triangle cannot exist.
The altitude line is perpendicular to the base and bisects the apex of the isosceles triangle.
Yes either an isosceles triangle or an equilateral triangle
yes
Its like an isosceles triangle that has been cut in half parrllel to its base
It's impossible.
yes it is possible to do that.
Yes to both
An isosceles triangle has 3 sides 2 of which must be equal in length.
you draw it with 2 sides of the same length and 1 that isn't the same as the others
It certainly can be. To draw one, draw a very flat "V" , one with a very wide angle, then connect the top to make a triangle.
If by regular, you're referring to a regular polygon which has all sides equal length, and all angles equal, then an equilateral triangle is a regular triangle. If you draw a scalene triangle or an isosceles triangle then it will not be equilateral.
