Pythagoras
A isosceles triangle has 2 sides that are the same length and a scalene triangle has no sides that are the same.
The third angle is 30°, and there's no way to determine the lengths of the sides from the information given.
yes. there is no way you can draw a triangle without three sides.
A scalene triangle has sides of different lengths while an equilateral triangle has sides of equal lengths
This is called an "equilateral triangle." A good way to remember its name is to remember that all of its sides are "equal."
they all have three sides
Every triangle has.
It is a congruence theorem. There are several of them and they are not all numbered the same way.
no, it is'ntNo. An easy way to determine this is if the sides satisfy the equation a2+ b2= c2.a2+ b2= c2 42+72=82 16+49=64 65=6465 does not equal 64 there for it doesn't satisfy the equation and is not a right triangle.
A triangle has three sides, while a parallelogram has four.
A triangle cannot have two parallel sides. In order for a figure to be a triangle, it must be a closed figure with three sides and three angles. If two of the sides were parallel, there is no way the figure could be closed by only one other line.
the one with equal sides the whole way around. they also have equal angles too.
