The sum of the interior angles on an Obtuse Triangle is 1800 . This is true of ALL triangles.
An obtuse triangle must have two acute angles and these can be congruent.
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
180 degrees minus interior angle = exterior angle and that the 3 exterior angles of a triangle add up to 360 degrees.
