What type of quadrilateral has two 80 degree angles and two 100 degree angles?
It is a parallelogram or a rhombus
Is a 200 degree angle an obtuse angle?
No, a 200 degree angle is a reflex angle. Reflex angles are angles that measure more than 180 degrees.
Two angles of a triangle each measure 70 what is the measure of the third angle in degree?
The sum of the angles is 180 degrees in any triangle. So 180-140 is 40 and the third angle is 40 degrees.
What are two angles called with a measure of 90 degrees?
The question isn't clear. If the sum of the two angles is 90 degrees, then they're called "complementary angles". If each one is a 90-degree angle, then they're called "two right angles".
What are the opposite angles of a quadrilateral inscribed in a circle?
A quadrilateral is inscribed in a circle it means all the vertices of quadrilateral are touching the circle. therefore it is a cyclic quadrilateral and sum of the opposite angles in cyclic quadrilateral is supplementary. suppose if one angle is A then another will be 180 degree - angle A.
Three angles of a quadrilateral measure 80 degrees 100 degrees and 55 degrees what is the measure of the fourth angle?
80 degree
Can a quadrilateral have two angles that measure 90 degrees?
yes!! a square! a squares angles are all 90 degrees. and a quadrilateral with 2 90 degree angles, and 1 with 40 one with 50. very possible.
Is it possible for each angle on a quadrilateral to measure more than 100 degree?
No because the 4 interior angles of a quadrilateral add up to 360 degrees
Interior angle of a convex quadrilateral?
The following are angles in a convex quadrilateral: Angle A = 80 degrees Angle B = 98 degree Angle C = 70 degrees What is the measure of the missing angle?
Two of the angles in a parallelogram each measure 75 degree what is the measure of the other two angles?
Always remember that a quadrilateral's (in this case, a parallelogram's) 4 angles must have a sum of 360 degrees. A quadrilateral has a pair of congruent angles. In this case, if a quadrilateral had 2 sides that have 75 degrees, the other 2 must be congruent, and the sum of all 4 angles must be 360.Let x = 1 of the remaining 2 angles (it doesn't matter which one, because they have the same measure)2x + (75+75) = 3602x + 150 = 3602x = 210x = 105The other angles are both 105 degrees.
Which polygons is the sum of the measure of the angles is 360 degree?
A quadrilateral (4-sided polygon).
A quadrilateral has a 50 degree 70 degree and a 150 degree angle what is the measure of the fourth angle?
90 degrees
What type of quadrilateral has two 80 degree angles and two 100 degree angles and why?
It could be a parallelogram because opposite angles are equal and its 4 interior angles add up to 360 degrees
The common unit to measure angles is called what?
Degree.
What is a degree measure of an angle in a reglar hexagon?
Interior angles: 120 degrees Exterior angles: 60 degrees
What does a protractor measure?
A protractor measures the degree of angles and circles.
What is the angle of a quadrilateral?
There are 360 total degrees in a quadrilateral. A square has 4 90 degree angles, and 90x4=360. To explain further, a square with 4 right angles (or 90 degrees), will have 180 degrees when cut in half, so the full square is 180x2=360.
