What triangle has at least two sides that are parallel?
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.
Can a triangle have to right angles?
NO, in order for a triangle to have two right angles, it would also have to have two parallel sides. This is impossible, as these two side would stretch into infinity and never close the triangele
What is the measure of the third angle of 79 and 52?
In order to answer this question it is necessary to assume that it is about the third angle of a triangle. If that is the case then it is 180 - (79 + 52) = 49 degrees.
How many order of rotation does an Isosceles Triangle have?
