How do you find the circumcenter of different types of triangle using cutting and folding method?
Suppose you have a triangle whose vertices are A, B and C, and the sides opposite these vertices are a, b and c, respectively. Cut out the triangle. Fold it so that vertex B meets vertex C. Mark the point where this fold is on side a. Mark this point as D and fold along AD. Fold it so that vertex A meets vertex C. Mark the point where this fold is on side b. Mark this point as E and fold along BE. Fold it so that vertex A meets vertex B. Mark the point where this fold is on side c. Mark this point as F and fold along CF. The three folds, AD, BE and CF meet at the circumcentre. You do not need all three - any two of them will do.

Why do all angles in a triangle add up to 180?
Draw two parallel lines (with points marked D and E on one, and F and G on the other). Mark point A on one line between D and E, and mark two points B and C on the other line between F and G. Join ABC to for a triangle: D_____________A_________________E ← point labels ------->---------+---------------------- ← first of the parallel lines _______________/\__________________ ______________/__\_________________ _____________/____\________________ ____________/______\_______________ ------->----+---------+---------------- ← second of the parallel lines F________B__________C__________G ← point labels (The underscores are there to keep the diagram in place - think of them like lines on the page of an exercise book.) Angles BAD + BAC + CAE add up to 180° as they are three angles on a straight line. Now angle ABC is the same as angle BAD as they are alternate (Z) angles Similarly, angle ACB is the same as angle CAE as they are alternate (Z) angles So substituting for equal angles, this gives: BAD + BAC + CAE = 180° → ABC + BAC + ACB = 180° But these three angles are the angles of the triangle ABC; thus the sum of the angles in a triangle is 180°.
How do you draw square root of 2 on a number line?
At the point 1, draw a perpendicular to the number line. Mark of a length of 1 unit on this line: call that point A.From the 0 on the number line, using a pair of compasses, measure the arc OA and use that length to mark the number line at sqrt(2).Rationale:You have a right angled triangle, with its right angle at the point 1. The base is 1 unit and the vertical height is 1 unit. So, by Pythagoras, the line from 0 to A is sqrt(2) units.At the point 1, draw a perpendicular to the number line.

How can you tell if three numbers equal a right triangle?
A right triangle is a triangle that has one 90 degree angle, and 2 other angles. Some special ones are 45-45-90, and 30-60-90. The sum of the angles in a triangle will always = 180 degrees. Since we know a triangle has 3 angles, and in particular, a right triangle has a 90 degree angle. We can say 180 degrees - 90 degrees = the other 2 angles. Add the other 2 angles in your triangle. Usually one is given as 90 degrees, or has a small square mark in the corner of the triangle to indicate that it is a right triangle. Once you add the other 2 angles, see if they add up to 90 degrees. If they do, you have a right triangle. If they do not, you either do not have a right triangle OR your triangle is broken and all 3 angles do not add up to 180 degrees.

How do you construct a equilateral triangle in a circle?
You will need... A set of compasses (for drawing the circle), and a straight edge. First, draw the circle. Then - put the point of the the compasses on the line. Mark the circle where the pencil crosses it. Place the point on this intersection and repeat the action until you're back at your starting point. Now - using the straight edge, join every alternate point to each other - forming an equilateral triangle.
How do you get a beauty mark?
it usually scabs over and scars.
What happens if you get a pimple under a beauty mark pop it and a scab forms over the beauty mark and when peeled off the beauty mark goes away with it?
i once picked at my mole and it bled and and i thought it went away, but it somehow grew back. so my assumption is that unless you completely got rid of the beauty mark (i think only a professional can do that and i dont recommend it cause you might leave a scar) its not very likely that the beauty mark will go away. im sorry. but you can get it removed really easily and it doesnt cost too much if you just have it cut off.
What does an exclamation mark inside a triangle mean?
