Strictly speaking it is an irregular polygon because all of its 3 sides are not equal because it has only two equal sides.
As it wouldn't be a triangle. If you forced this, you would then have formed an irregular polygon square missing a side.
The contrapositive would be: If it is not an isosceles triangle then it is not an equilateral triangle.
If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle.If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle.If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle.If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle.
I would call it an irregular octagon, or an irregular 8-sided polygon.
that would be an isosceles triangle, although the def. of an isosceles triangle is: a triangle that has at least 2congruent sides.
The only requirement for an isosceles triangle is that two sides be the same length and one be different. It is possible for an isosceles triangle to have two perpendicular legs. It would be right and isosceles.
You would call it an irregular polygon. Afraid not. There is no specific name, except in the case of a triangle: scalene. You should not call it simply an irregular polygon, because a regular polygon implies that ALL sides are equal and ALL angles are equal. So a rhombus, where all four sides are equal, is still irregular.
The contrapositive of the statement "If it is an equilateral triangle, then it is an isosceles triangle" is "If it is not an isosceles triangle, then it is not an equilateral triangle." A diagram representing this could include two circles: one labeled "Not Isosceles Triangle" and another labeled "Not Equilateral Triangle." An arrow would point from the "Not Isosceles Triangle" circle to the "Not Equilateral Triangle" circle, indicating the logical implication. This visually conveys the relationship between the two statements in the contrapositive form.
Any isosceles triangle will have 2 sides that are the same length so this would be an isosceles triangle.
-- Some mathematicians define an 'isosceles' triangle as one with at least twoequal sides. They would say that equilateral triangles are isosceles.-- Other mathematicians define an 'isosceles' triangle as one with exactly twoequal sides. They would say that equilateral triangles are not isosceles.
No, an isosceles triangle can not be a right triangle, because a right triangle has an angle of 90 degrees angle, and two angles of 45 degrees. An isosceles triangle has all acute angles, therefor, making it an acute triangle, so no, an isosceles triangle is not, i repeat not, a right triangle.
To represent the contrapositive of the statement "If it is an equilateral triangle, then it is an isosceles triangle," you would first identify the contrapositive: "If it is not an isosceles triangle, then it is not an equilateral triangle." In a diagram, you could use two overlapping circles to represent the two categories: one for "equilateral triangles" and one for "isosceles triangles." The area outside the isosceles circle would represent "not isosceles triangles," and the area outside the equilateral circle would represent "not equilateral triangles," highlighting the relationship between the two statements.
