How do you find the unknown side of a quadrilateral with 3 known sides and 4 angles?

Several options:
- Draw it and measure the missing side.
- Use coordinate geometry. You can draw the base and two of the sides since you know the angles that these lines make and their lengths. You therefore know their upper end points and so calculating the length of the fourth side is trivial.
- Consider the triangle ABC. Sides AB and BC are known as is angle ABC. So you can use the sine rule to calculate AC and angles CAB and ACB. Angle DAB is known so angle DAC = DAB - CAB, angle ACD = BCD - ACB. In triangle ACD, two angles are known so all three are known. Use the sine rule again to find CD.

Is an isosceles triangle a quadrilateral?
No. Triangles have three angles and three sides. A quadrilateral has four angles and four sides.
How many angles does a quadrilateral have?
A quadrilateral has four angles. There are always the same number of angles as there are sides, so since a quadrilateral has four sides it must also have four angles.A quadrilateral doesn't "do" any angles. However, it has four angles. (If that is what you wanted to know.)
What is the definition quadrilateral?
A quadrilateral is a polygon with four sides and angles.
What is a quadrilateral with four right angles and equal sides?
A square is a quadrilateral with four equal sides and four right angles.
Does a quadrilateral have exactly 2 congruent angles?

What is a quadrilateral with no equal sides and 4 right angles called?
It's impossible for a quadrilateral to have no equal sides and have right angles.
Which quadrilateral has 4 congruent sides and 4 right angles?
A quadrilateral has 2 pair of congruent angles and 4 congruent sides. What is the name of the quadrilateral
If a quadrilateral has four congruent sides but its adjacent angles are not congruent then the quadrilateral is a?
An impossibility. By definition a quadrilateral with 4 congruent sides must have congruent adjacent angles.
