Does a kite have an obtuse angle?
Yes, a kite typically has at least one obtuse angle. A kite is a quadrilateral with two distinct pairs of consecutive, congruent sides. In a kite, the angles between the non-congruent sides (the angles opposite the longer and shorter sides) are usually not congruent. One of these angles can be obtuse, depending on the specific shape of the kite. However, it's important to note that a kite can also have acute angles, but it must have at least one obtuse angle.
Which quadrilaterals have two obtuse angles?
Every parallelogram and most trapezoids have.Oh wait! It seems to me that every quadrilateral, regular or irregular, that'snot a rectangle and not concave, must have at least two obtuse angles.
Can you have a quadrilateral with three acute angles?
Yes you can, as long as the four angles (obviously three of which will be less than 90 degrees) end up with a sum of 360 degrees, meaning there will have to be at least one obtuse angle in a non-square quadrilateral.
Do triangles have at least two obtuse angles?
No. A triangle can have only one obtuse angle. A triangle must have at least two acute angles
What do the triangles look like and what are the names?
Equilateral triangle = All sides congruent Scalene triangle = No sides congruent Isosceles triangle = At LEAST two sides congruent Right triangle = Triangle with one right angle Obtuse triangle = Triangle with ONE obtuse angle Acute triangle = Triangle with ALL acute angles
Is a rhombus acute?
No. Except for the case of a square (a special case of rhombus), a rhombus will have 2 congruent acute angles, and 2 congruent obtuse angles. The square has 4 right angles. In fact, every quadrilateral will have either all 4 angles equal to right angle (square and rectangle), or will have at least 1 obtuse angle (also at least 1 acute).
Does a kite have an obtuse angle?

What is one way to determine if a quadrilateral has congruent angles?
If it has at least one set of parallel sides, then at least one set of angles are congruent
Which type of quadrilateral always has at least three congruent angles?
A rectangle or a square.
If you know that two of the angles in a quadrilateral are obtuse then what is true about the other two angles and Explain?
You know that at least one of them must be acute. A quadrilteral can have three obtuse angles, but not four.
Which quadrilaterals have two obtuse angles?
Every parallelogram and most trapezoids have.Oh wait! It seems to me that every quadrilateral, regular or irregular, that'snot a rectangle and not concave, must have at least two obtuse angles.
Which of the following is not a sufficient condition for concluding a quadrilateral is a parallelogram?
at least one pair of opposite sides is parallel
What are the names of the triangles and how can you tell?
right triangle forms a 90 degree angle scalene triangle has no congruent sides isosceles triangle has at least 2 congruent sides equilateral triangle has 3 congruent sides acute triangle all angles measure less than 90 degrees and the obtuse triangle contains 1 obtuse angles.
Can you have a quadrilateral with three acute angles?
Yes you can, as long as the four angles (obviously three of which will be less than 90 degrees) end up with a sum of 360 degrees, meaning there will have to be at least one obtuse angle in a non-square quadrilateral.
Can a quadrilateral be made with 3 acute angles and 1 right angle?
Not possible... The internal angles of a quadrilateral always total 360. If you MUST have an angle of 90 degrees - the remaining angles must total 270. At least one of the remaining angles will always be obtuse.
Classification of triangle?
Classification of triangles according to sides: -Scalene Triangle - a triangle with no 2 congruent sides. -Isosceles Triangle - a triangle with at least 2 congruent sides. -Equilateral Triangle - a triangle with 3 congruent sides. Classification of triangles according to angles: -acute triangle - a triangle with 3 acute angles. -right triangle - a triangle with one right angle. -equiangular triangle - a triangle with 3 congruent angles. -obtuse triangle - a triangle with one obtuse angle.
Do triangles have at least two obtuse angles?
No. A triangle can have only one obtuse angle. A triangle must have at least two acute angles
