A right angled triangle has one angle that is 90 degrees. The other two must be acute and may (but need not) be equal to one another.
An acute triangle has all its angles less than 90 degrees. They may be all the same, two of them the same or all different.
An isosceles triangle has two angles the same (and hence acute). The third angle can be acute, right or obtuse.
A scalene triangle has three unequal angles. Two of them must be acute but the third may be acute, right or obtuse.
an obtuse scalene has an obtuse(more than 90 degrees)angle and 0 same length sides and a acute isosceles triangle has one acute,less than 90 degree angle and has 2 same length sides
Equilateral, Isosceles or Scalene. For the latter two they could be acute or right angled
Can a right triangle be both scalene and isosceles? Explain
Sometimes an isosceles triangle but never a scalene triangle with 3 interior acute angles.
Yes to both
7 Equilateral, Isosceles, Scalene, Acute, Right, Obtuse, and Right Scalene
They both have 3 sides but an isosceles triangle has two equal sides whereas an acute triangle with different acute angles has no equal sides and is said to be a scalene triangle, or an acute triangle with three equal acute angles (of 60° each) and three equal sides is called an equilateral triangle.
An acute scalene triangle has none. An acute isosceles triangle has one and an [acute] equilateral has three.
