An obtuse triangle must have two acute angles and these can be congruent.
The sum of the interior angles on an Obtuse Triangle is 1800 . This is true of ALL triangles.
The base angles are always congruent.
"The sum of the angles in a triangle equal 180 degrees" is a true statement.
That it has a 90 degree angle and two equal 45 degree angles
The two equal angles each measure 45 degrees
An obtuse triangle has 1 obtuse angle and 2 acute angles which add up to 180 degrees.
The two acute angles are always equal.
An equilateral triangle is also isosceles.Improved Answer:-They are both triangles whose 3 interior angles add up to 180 degrees and an equilateral triangle has 3 equal angles with 3 equal sides whereas an isosceles triangle has 2 equal angles with 2 equal sides
