What are the 7 types of triangles?
The seven types of triangles are Isosceles, equilateral, scalene, equiangular, acute-angled, obtuse-angled, and right-angled
Does a obtuse angled isosceles triangle have congruent side?
All isosceles triangles must have two congruent sides otherwise it is not isosceles. Whether it is acute angled, right angled or obtuse angled is irrelevant.
Which types of triangles can be formed by taking the cross-section of a cube?
Equilateral, Isosceles or Scalene. For the latter two they could be acute or right angled
What congruent shape can 2 right-angled triangles make?
Isosceles triangle
Are right triangles always isosceles?
No. For example a 3, 4, 5 cm triangle is right angled but not isosceles.
Do triangles have all equal sides?
only equilateral triangles the other three, scalene isosceles and right angled, do not
How many right angles does a isosceles triangle have?
It can only have a maximum of one- and that is only if it is a right-angled isosceles triangle. ----------------------------------------------------- Yes not all isosceles triangles are right angle triangles - this is a special case.
Does a right angled triangle have a line of symmetry?
yes * * * * * Usually, no. Only isosceles right angled triangles have a line of symmetry.
How many right angles does a isosceles right triangle have?
It can only have a maximum of one- and that is only if it is a right-angled isosceles triangle. ----------------------------------------------------- Yes not all isosceles triangles are right angle triangles - this is a special case.
Are scalene and isosceles triangles similar?
No because they are different types of triangles
Are acute-angled triangles similar?
Similar in the number of sides but not congruent
Are two isosceles triangles similar?
Yes, as long as they're both isosceles
