Is 18 toothpicks enough to form 5 quadrilaterals if no quadrilateral shares a toothpick with another quadrilateral?
Yes, if a generic square is made, and a toothpick along the vertical and horizontal line of symmetry, and then another generic square. 18 is enough to form it, and so is any double-digit number.JK they cant share any. But maybe, if you use more than toothpicks
What is the sum of the measures of the exterior angles of a decagon?
It is generally accepted to count only one vertex per side when calculating the sum of exterior angles. If this is what you mean, then for every convex polygon (all angles point away from center), the sum is always 360º.However, you can also count two vertexes per side, so the sum would then be double, or 720º.

What conjectures in Classic or Euclidean Geometry have been proved from elementary axioms?
All the below listed conjectures (first letter C of Conjecture) can be proved using the Euclidean axioms of geometry. They can be used to teach or learn geometry. In this way one "discovers" the power of the Euglidean axioms.Some may be beyond this goal as they stand, as the definitions of key concepts is not included (e.g., centroid [C15], or "vertical" angle [C2], sometimes called a "right" angle.C1 Linear Pair: If two angles form a linear pair, then they are supplementary and total 180 degrees.C2 Vertical Angles: If two angles are vertical angles (right

How many sides and angles does a decagon have?
A decagon is a polygon with 10 sides and 10 angles. Each angle in a regular decagon measures 144 degrees. The sum of the interior angles of a decagon is 1440 degrees. Decagons have lines of symmetry that pass through the center of the shape and divide it into two equal halves.
Explain that the sum of interior angle is equal to quadrilateral 360?
Any quadrilateral may be split into two triangles; the sum of internal angles of any triangle is 180 degrees; so the sum of internal angles of a quadrilateral will then be the double of the sum of internal angles of a triangle: 180 x 2 = 360.

What is double angle in x rays diffraction?
it has lots of angles man don't u get it
What is double 180?
Double 180 is 360. When you double a number, you multiply it by 2. In this case, when you double 180, you get 180 x 2 = 360. 360 degrees is a full circle in terms of angles.
