How do you find the last angle of a quadrilateral?
Subtract the 3 known angles from 360 to find the 4th angle.
What is a quadrilateral with 3 acute angles and 1 obtuse angle?
A quadrilateral with 3 acute angles and 1 obtuse angle is known as a scalene trapezoid. In this type of quadrilateral, three of the angles are less than 90 degrees (acute angles), while one angle is greater than 90 degrees (obtuse angle). The sides of a scalene trapezoid are of different lengths, and the opposite sides are not parallel. This distinguishes it from other types of quadrilaterals such as rectangles or parallelograms.
What is a quadrilateral where each angle is a right angle?
A rectangle is a quadrilateral with 4 sides and 4 right angles. A square is a special form of rectangle, and it meets that criterion. But it is also equilateral, meaning its sides are all the same length (are all equal). It is a rectangle or a square. A square is a special type of rectangle with all sides having equal length. Here is a a nice chart showing the quadralaterals. http://content.answers.com/main/content/wp/en/f/f1/Quadrilateral_hierarchy.pngA quadrilateral where each angle is a right angle is known as an oblong.
What angle measure is a kite?
I can answer this if the question concerns Penrose tiling using "kite" and "dart" tiles. The "kite" is a quadrilateral whose four corners have angles of 72, 72, 72, and 144 degrees. The "dart" is a non-convex quadrilateral whose four interior angles are 36, 72, 36, and 216 degrees. If however if the questioner want to determine an unknown angle in of a general kite quadrilateral (two sides of length a and two sides of length b, not a parallelogram) when the length of all sides and one angle is known, then the equation [which is too complex for me to easily transcribe] can be found in the Geometry Atlas http://www.geometryatlas.com/entries/153 I can answer this if the question concerns Penrose tiling using "kite" and "dart" tiles.

How do you determine the measurement of a missing angle in a angle?
To find the measure of an angle, you need to know the size of the entire angle and the other angles within the angle. Then, you subtract the smaller, known angles from the entire, large angle and you should get the measure of the missing angle.
One Fourth of a right angle?
A right angle measures 90 degrees, so one fourth of a right angle would be 90 degrees divided by 4, which equals 22.5 degrees. This is known as a "quadrant" in geometry, as it represents one of the four equal parts of a right angle. In trigonometry, this angle would fall in the first quadrant, where both the x and y coordinates are positive.
What is a concave quadrilateral?
A concave quadrilateral would be a non-convex quadrilateral. * * * * * Also known as delta or arrowhead or chevron.
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.
How do you find the fourth side of a quadrilateral with 3 known sides?
You cannot.All that can be said with certainty is that the length of the fourth side can have ANY positive value between (a) the longest minus the sum of the other two sides, and (b) the sum of all three sides.
What instrument could sailors use to determine their location based on the position of the sun in relation to the horizon?
Sailors could use a sextant to measure the angle between the sun and the horizon. By comparing this angle with known tables, they can determine their latitude at sea.
How do you find the size of an angle without using a protractor?
If the angle is a lone, random angle, I believe you would need a protractor to determine the precise size of the angle (in "degrees"). However, you could, in this case, roughly guess as to whether the angle is acute, obtuse, or right (if the little rectangle is shown in the angle). Of course, if an angle is in a position where one can determine its measure using known postulates or theorems, finding the size of this angle becomes much easier. For example, if you know the measure of one angle and you must determine the measure of another angle, but these two angles are vertical angles, or are corresponding angles (by the corresponding angles postulate), you can indeed determine the measure of this angle without a protractor. Additionally, another example is that if you knew a pair of angles were either supplementary angles, complementary angles, or a linear pair, and you were given the measure of one of these angles, you could determine the measure of the other angle without a protractor. Therefore, it depends on the angle you're looking at.
