How do you draw a quadrilateral with three internal acute angles and one reflex angle?
A bit like a chevron or an arrowhead.
Can a quadrilateral have exactly one right angle?
Yes I had a question on my maths test asking me to draw a quadrilateral with one right angle, so yeah, a quadrilateral can have exactly one right angle lol But i havent got a clue how to draw one :S
How do you draw a reflex angle that measures 245 degrees?
If you have a 360o protractor, you draw one side of the angle, measure 245o round from this line and then draw in the other side of the angle, and then mark a small arc around the reflex angle. If you only have a 180o protractor, you start again by drawing one side of the angle; then you measure 360o - 245o = 115o the "wrong way" round from this line to give the 245o the right way and draw in the other side, and then mark a small arc around the reflex angle.
Draw a pentagon that has exactly one interior reflex angle?
An arrow head that is flat at tip instead of pointy.
What is the opposite side of a reflex angle?
A reflex angle is one that is more than 180 degrees but less than 360 degrees. If the reflex angle measured 190 degrees, then there would be a 170 degree, or obtuse, angle opposite it. If the reflex angle measured 270 degrees, then there would be a 90 degree, or right, angle opposite it. If the reflex angle measured 300 degrees, then there would be a 60 degree, or acute, angle opposite it. It helps to draw or picture these angles as sectors of a circle.

Is it possible to draw a quadrilateral with a reflex angle and an obtuse angle?
Yes, it is possible to draw a quadrilateral with a reflex angle and an obtuse angle. A reflex angle measures more than 180 degrees, while an obtuse angle measures between 90 and 180 degrees. To create a quadrilateral with these angles, you can draw a shape with one reflex angle (greater than 180 degrees) and one obtuse angle (between 90 and 180 degrees), along with two acute angles (less than 90 degrees).
Can quadrilateral have more than one reflex angle?
No.
What quadrilateral has two pairs of equal lines one pair of equal angles and one reflex angle?
This is an arrowhead quadrilateral.
Can a quadrilateral have exactly one right angle?

How do you draw a reflex angle?
When an angle is drawn a small arc is normally placed near the vertex between the arms to show the angle. A reflex angle is one greater than 180°, so draw the two arms as normal and then draw a small arc around the vertex of the angle "outside" the arms of the angle, ie around the angle which is greater than 180° If the problem is how to draw the reflex angle with a protractor that only goes up to 180°, then note that "360° - the reflex angle" gives an angle which is less than 180° and can be measure by the 180° protractor. Draw one arm of the angle, measure the calculated angle (eg if the reflex angle was 200°, 360° - 200° = 160°, so measure 160°), draw the other arm, and then draw an arc around the vertex "outside" the arms to show the reflex angle (in the example, the 200° angle).
What quadrilateral has one reflex angle and 2 pairs of adjacent sides equal?
A chevron.
Could a concave quadrilateral have more than one reflex angle?
A reflex angle is over 180 degrees, but the sum of the angles in a quadrilateral, concave or convex, is 360. Therefore, since 180+180=360, you can't have any more degrees even without the amount over 180 that the reflex angle has.
How do you contruct a reflex angle?
A reflex angle is an angle greater than 180 degrees and less than 360 degrees. To construct one draw two lines at an angle and draw the angle measurement circle around the side you normally don't do it on.
What is a quadrilateral with two pairs of equal adjacent sides axis of symmetry and one reflex angle?
An arrowhead
How do you draw a reflex angle that measures 245 degrees?
If you have a 360o protractor, you draw one side of the angle, measure 245o round from this line and then draw in the other side of the angle, and then mark a small arc around the reflex angle. If you only have a 180o protractor, you start again by drawing one side of the angle; then you measure 360o - 245o = 115o the "wrong way" round from this line to give the 245o the right way and draw in the other side, and then mark a small arc around the reflex angle.
Can a quadrilateral have a reflex angle?
Yes. One. The quadrilateral then looks a bit like a boomerang, according to my daughter. We had to establish this answer in her year 7 maths homework.
