- Polygon 42
Which polygon has 42 more diagonals than sides? - Octagon side perimeter
The perimeter of the regular octagon is 8u + 16 cm. Calculate the side if u = 0.5 cm. - Each side Each side of a regular polygon is 5.2 m, and its perimeter is 36.4 m. Find the number of sides of a polygon.
- A pentagon
Find the perimeter of a pentagon whose sides measure 11/2 cm, 7/4 cm, 3 1/3 cm, 2 1/3 cm and 2 1/12 cm. - Angles of a hexagon
Find the interior angles of a hexagon if the sizes of the angles form an arithmetic sequence and the smallest angle is 70°. - Polygon diagonal sides
Determine the type of polygon if the number of all diagonals is 90. (Write down the number of its pages.) - Sum of inner angles
Prove that the sum of all inner angles of any convex n-angle equals (n-2).180 degrees. - Circumference of a polygon
Calculate the length of the side and the regular 15-gon if you have given its circumference o = 745. - Ten persons
Ten persons, each person, make a hand to each person. How many hands were given? - Regular n-gon
In a regular n-angle polygon, the internal angle is 144 degrees. Find the number n indicating the number of sides of this polygon. - Ferdinand
Ferdinand went from place A to place B and from there to place C. A is 7.2 km from B, and B is 11.7 km from C. Albert went from place A to place D and from there to place C. D is 9.1 km from A and C is 10.8 km from D. Who traveled more and by how much? - Guests - party
There are 13 guests at a party. They clink their wine glasses with each other. How many clinks will we hear in total? - Each with each
Five pupils from the 3A class played table tennis. How many matches did they play with each other? - Interior angles - sum
For the sum s of the interior angles of a polygon, where n is the number of its sides, the relation s=(n−2)⋅180 degrees applies. How many sides does a polygon have if the sum of its interior angles is 900°? - The interior
The interior angle of a regular polygon is x. If x is 9° less than the average of 153° and 145°, find the number of sides of the polygon. - n-gon
Gabo draws an n-gon, in which angles are consecutive members of an arithmetic sequence. The smallest angle is 120° biggest 160°. How many sides have Gabo's n-gon? - Tournament match calculation
The long-term volleyball tournament is played one-on-one. So far, 11 teams have entered the competition. How many matches will be lost when two teams unsubscribe? - Pupils - dataset
