What is the fifth postulate of Euclid's?
The parallel postulate: "That, if a straight line falling on two straight lines make the interior angles on the same side less than two right angles, the two straight lines, if produced indefinitely, meet on that side on which are the angles less than the two right angles."
How can we rewrite Euclid's fifth postulate?
Euclid's fifth postulate: If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough.It can be rewritten: If two lines are drawn which intersect a third at angles of 90 degrees, the two lines are parallel and will not intersect each other.It has also been rewritten as Playfair's axiom:In a plane, given a line and a point not on it, at most one line parallel to the given line can be drawn through the point.
What is one fifth of a circle?
One fifth of a circle is equal to 360 degrees divided by 5, which is 72 degrees. This means that if you were to divide a circle into five equal parts, each part would measure 72 degrees. This calculation is based on the fact that a full circle is 360 degrees.
What is the fifth digit of pi?
The fifth digit of pi is 5. The first 10 digits are 3.141592653
What is a fifth of an acre?
An acre is a unit of area commonly used in the United States and is equal to 43,560 square feet. Therefore, a fifth of an acre would be one-fifth of that area, which is equal to 8,712 square feet. To put it in perspective, a fifth of an acre is roughly equivalent to a square plot of land with sides measuring approximately 93.3 feet.
If four angles of a pentagon have measures of 93 87 97 and 153 find the measure of the fifth angle?
5th angle of the pentagon: 540-93-87-97-153 = 110 degrees
Does a pentagon have an obtuse angle?
Yes it must have at least one (really, it needs two or more). The sum of the interior angles in a pentagon is 540°. If you had 4 angles @ 90°, then the fifth angle would need to be 180°, which is a straight line, then it would be a rectangle, not a pentagon, so you need at least two angles, greater than 90°.
How do you find the value of the fifth angle in a pentagon given angles 112 102 118 and 107?
There are 540 interior degrees in a pentagon So: 540-112-102-118-107 = an angle of 101 degrees
What is the measure of the angle created by one-fifth of a counterclockwise revolution?
360/5 = 72 degrees or 2*pi/5 radians
What is fifth grade geometry?
It depends on the state you're in. In California, it's how to measure angles and degrees, names of shapes and some stuff about triangles.
How do you measure one fifth of water?
You have not specified the quantity of water. You cannot measure one fifth of an unspecified quantity.
What is four congruent angles?
They are four angles which are equal. They could be 4 angles of a pentagon measuring 100 degrees, where the fifth measures 40 degrees.
How many milaliter are in a fifth?
There is no such measure.
How many angles are formed by 12 distinct rays with a common endpoint?
There are 66 angles formed by 12 distinct rays with a common endpoint. The first ray by itself doesn't make an angle, the second ray makes 11 distinct angles, the third ray makes 10, the fourth 9, the fifth - 8, the sixth - 7, the seventh-6, the eighth - 5, the ninth- 4, the tenth - 3, the eleventh - 2, and the twelfth - 1 (it makes an angle with the first ray).
What figure has four right angles and any types of angles?
A polygon with six or more sides, in which four of the angles are right angles and the other angles are not. These others are of any type - as required. It cannot be a pentagon because, if 4 angles are right angles, the fifth would be 180 degrees!
Who was the British king that asked for aid from the Angles and Saxons in the fifth century?
Vortigern. Delamare! Vol.1
Which measure is the greater one fifth of a gill or 25 mls?
25 mls
