No
Two colors that complement each other and can be used together in a color scheme are blue and orange.
Yes, an obtuse triangle can have two congruent angles, where for the obtuse angle measuring A degrees, each of the two other angles measures (180-A)/2.
name two obtuse vertical angles.
yin and yang
Yes providing that they add up to 90 degrees
they can be obtuse say ther are two lines intersecting two of the angles are acute (50degrees) that means the other pair must be obtuse 180-50=130 so the other two angles are obtuse with a measurement of 130degrees
name two obtuse angles in the figue
Trapezoids ALWAYS have at least one obtuse angle (if they have two right angles, then there will only be one obtuse angle), usually two (in any other circumstance, they will have two obtuse and two acute 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.
Vertical angles are, by definition, equal. So if one is obtuse then so is the other.
Yes. A triangle can have only one obtuse angle. The other two angles will always be acute.
In an obtuse triangle, one angle is obtuse and the other two are acute. "The buildings are arranged in an obtuse triangle and occupy most of the long, thin parcel of land."
