What has at least one vertex?
a scalene triangle a scalene triangle
What is a triangle with no equal sides and no equal angles?
A triangle with no equal sides and no equal angles is called a scalene triangle. In contrast, a triangle with equal sides and equal angles is called an equilateral triangle. A triangle with two equal sides and two equal angles is an isosceles triangle.
Can an scalene triangle have an acute angle?
Yes at least 2
What is a triangle with no congrent sides?
That is a scalene triangle. An isosceles triangle has at least 2 congruent sides and an equilateral triangle has 3 congruent sides.
What is has no lines of symmetry and at least one right angle?
A right scalene triangle
What polygon has at least one pair of sides or angles that is not congruent?
That would have to be a scalene triangle.
You are a polygon you have the least amount of sides a polygon can have All of your angles are different What shape are you?
A scalene triangle
A triangle with at least two equal sides?
That is an isosceles All equal sides is called an equilateral triangle 2 equal sides is an isosceles No equal sides is a scalene triangle
What is the measure of an scalene triangle?
There are at least 8 different "measures" that we can think of for any triangle: three sides, three angles, a perimeter, and an area. We can't guess which one you're looking for. A 'scalene' triangle is simply any triangle in which no two sides are the same length. That fact doesn't help us.
What triangle is formed with three sides of different lengths?
A scalene triangle. In a scalene triangle, there are no congruent sides or angles. In an isosceles triangle, at least two congruent sides and angles. In an equilateral triangle, all three sides and angles are congruent, with angles that always measure sixty degrees. Note: an equilateral triangle also classifies as an isosceles triangle, as it meets the definition of an isosceles triangle mentioned above.
What is the triangle that has the lengths of at least two sides?
An EQUILATERAL triangle has all three sides the same length. An ISOSCELES triangle has two sides with the same length. A SCALENE triangle has all three sides different lengths.
What does a right triangle and a scalene triangle have in common?
they are two dimensional shapesthey are trianglesthey have three sidestheir interior angles add up to 180 degreestheir exterior angles add up to 360 degreesthey have at least two sides of different lengthsRight triangle: three sided two dimensional shape with one right angleScalene triangle: three sided two dimensional shape with three sides of different lenghtsBeing Scalene and being Right are not mutually exclusive. A Scalene triangle can also be a Right triangle, and vice versa.
