Are consecutive angles in a parallelogram always congruent?
Not unless the parallelogram is a rectangle. In every parallelogram, consecutive angles are supplementary.
Can two obtuse angle be adjacent angles?
Two angles are adjacent if they have the same vertex, share a side and do not overlap. It is, therefore, perfectly possible for two obtuse angles to be adjacent. In fact, every pair of adjacent angles in a hexagonal tessellation (a honeycomb, for example), consists of a pair of obtuse angles (120 degrees).
Why can you not have two obtuse angles in a triangle?
-- The sum of all three angles inside every triangle is always 180 degrees. -- An obtuse angle is an angle with more than 90 degrees in it. -- So two obtuse angles have more than 180 degrees between them. -- So they can't both be in the same triangle, unless at least part of one of them is left hanging out.
How many acute angles does an obtuse triangle have?
Every triangle must have at least 2 acute angles, otherwise it is impossible to make the 3 sides connect.
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).
Are consecutive angles in a parallelogram always congruent?
Not unless the parallelogram is a rectangle. In every parallelogram, consecutive angles are supplementary.
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.
What kind of angles does a triangle have in it acute or obtuse?
Every triangle must have at least two acute angles. The third one can be acute, right (90 degrees), or obtuse.
Can two obtuse angle be adjacent angles?
Two angles are adjacent if they have the same vertex, share a side and do not overlap. It is, therefore, perfectly possible for two obtuse angles to be adjacent. In fact, every pair of adjacent angles in a hexagonal tessellation (a honeycomb, for example), consists of a pair of obtuse angles (120 degrees).
Are rectangles consecutive angles supplementary?
yes they are supplementary.... because every angle of a rectangle is 90 degrees... therefore consecutive 90 degrees would be 180 degrees therefore they are supplementary....
What is the measurement of every obtuse angle?
It depends on the angle not all obtuse angles measure the same. To measure an angle you use a protractor.
What shapes contain obtuse angles?
The most notable is a triangle, but every polygon can have an obtuse angle. An obtuse angle is anything measuring greater than 90 degrees.
Is it true that every angle of an acute angle is acute?
yes. to be and acute angle, all angles must be acute. Obtuse angles only one angle has to be obtuse. Right angles only need one too. Acute has to have every angle to be acute, if one angle is obtuse or right, it's automatically no an acute Angle anymore.
Is it possible for some triangles to have none exterior angle obtuse angle?
Yes, a Triangle can have 3 obtuse EXTERIOR angles of measure 120° ONLY in the case of an equilateral Triangle. OTHERWISE, a Triangle always has 2 obtuse Exterior angles and 1 acute Exterior angle.
Is it possible to draw a triangle with an acute angle and an obtuse angle?
Yes. Every triangle with an obtuse angle must have two acute angles.
What has an obtuse angle?
An obtuse triangle can have at most one obtuse angle.A quadrilateral can have up to 3.Every regular polygon (shapes with equal sides and angles) with more sides than a square has obtuse angles.PentagonHexagonHeptagonOctagonNonagonDecagon
Which shape has only two acute angles?
"z" has two acute angles a triangle can have 3 acute angles but also will have a angle >= 60degrees acute (also note for every acute angle a obtuse angle is formed the sum of the obtuse and acute angle will = 360) because of this a arrow is the only shape with two acute angles and 1 obtuse
