No.
Any triangle that has three equals sides must have three acute angles and is equilateral.
Any shape, other than a triangle can have a pair of perpendicular sides.
Any kind of triangle can have rational or irrational sides: acute angled, right angled or obtuse angled; equilateral, isosceles or scalene.
We'd need to know the number of sides. An equilateral triangle won't have any parallel or perpendicular sides. An equilateral quadrilateral will have two pairs of parallel sides which may or may not be perpendicular.
No.
An equilateral triangle doesn't have any perpendicular sides on it.
no a equilateral triangle does not have any perpendicular sides because the lines are joined together.
None because no triangle has any parallel sides.
Any triangle that has three equals sides must have three acute angles and is equilateral.
Any shape, other than a triangle can have a pair of perpendicular sides.
No two sides of a triangle are ever parallel, and althoughit isn't required, a triangle can have all acute angles.That isn't possible for any shape with more than 3 sides.
A scalene triangle is one of them
Any kind of triangle can have rational or irrational sides: acute angled, right angled or obtuse angled; equilateral, isosceles or scalene.
We'd need to know the number of sides. An equilateral triangle won't have any parallel or perpendicular sides. An equilateral quadrilateral will have two pairs of parallel sides which may or may not be perpendicular.
A scalene acute triangle is a triangle with all sides of different lengths and all angles less than 90 degrees. It does not have any equal sides or equal angles. Therefore, a picture of a scalene acute triangle would show three lines of different lengths connecting to form a triangle with three angles less than 90 degrees.
A scalene has three sides of unequal lengths, and all threes angles different.The largest angle defines the triangle¹:acute: a scalene triangle could have sides 6, 9, 10right angle: a scalene triangle could have sides 6, 8, 10obtuse: a scalene triangle could have sides 6, 7, 10So a scalene triangle could be any of acute, right angle or obtuse.¹In terms of acute, right angle or obtuse. Triangles can also be defined in terms of their sides: equilateral (all three sides equal), isosceles (two sides equals) or scalene (no sides equal)
