Example 1: A right triangle has one other angle that is 35º. What is the size of the third angle?
Solution:
Step 1:A right triangle has one angle = 90°. Sum of known angles is 90° + 35º = 125°.
Step 2:The sum of all the angles in any triangle is 180º. Subtract sum of known angles from 180°. 180° - 125° = 55°
Answer:The size of the third angle is 55°

parallelogram
What type of triangle has two equal obtuse angles giving reasons for your answer?
There is no triangle that has 2 equal obtuse angles because the 3 interior angles of any triangle must add up to 180 degrees and 2 obtuse angles would be over 180 degrees. It is possible for a triangle to have two equal acute angles in which case it would be an isosceles triangle.

2 acute and 2 obtuse
What type of angles do a parallelogram have?
2 Acute and 2 obtuse
Which 2-D shapes can have 2 acute angles and 2 obtuse angles?
With 2 acute and 2 obtuse angles it has 4 angles - the shape is a quadrilateral. The shape can be one of trapezium, parallelogram, rhombus, kite or a general quadrilateral. With the two acute angles next to each other (forcing the two obtuse angles to be next to each other) the shape can be either a trapezium or a general quadrilateral.
What shape has 2 right angles and 1acute angle and 2 obtuse angles?
A shape that has 2 right angles, 1 acute angle, and 2 obtuse angles is a quadrilateral. One possible example is a right trapezoid, where two angles are right angles, one angle is acute, and the last angle is obtuse. This combination of angles can create various quadrilateral shapes, but they must maintain the sum of interior angles equal to 360 degrees.
What triangle has 2 obtuse angles?
No triangle has 2 obtuse angles
Do trapezoids have 2 obtuse and 2 acute angles?
Trapezoids can have various angle configurations, but they do not necessarily have to have 2 obtuse and 2 acute angles. A trapezoid can have two acute angles and two obtuse angles, or it can have all angles being right angles in the case of a right trapezoid. The specific angles depend on the type of trapezoid and the lengths of the sides.
