Q1.
Make your own kite shape. (a) Start with a square piece of paper. (b) Take one corner of the paper and fold it towards the opposite corner, creating a sharp crease along the diagonal. (c) Open and fold the corner A inwards, aligning the edge with the crease you just made. (d) Repeat on the other side, folding the other corner B inwards to align with the crease at the centre. You have a kite shape!

Folding a square sheet of paper into a kite.
Answer

Follow the four steps exactly and a kite appears. Here is the same thing said in slower words.

  1. Start with a square sheet. If your paper is a rectangle, fold one corner across and tear off the extra strip to make it square.
  2. Make the middle crease. Fold the sheet so that one corner lands exactly on the opposite corner. Press hard along the fold, then open the sheet out. You now have a clear line from corner to corner. This line is the diagonal.
  3. Fold corner A in. Bring the edge next to corner A over so that it lies exactly along the crease. Press it flat.
  4. Fold corner B in the same way on the other side of the crease. Its edge also lies along the crease.
  5. Look at the outline. Two short sides at the top, two long sides at the bottom, and a mirror line down the middle. That is a kite.
A B 1. crease the diagonal 2. fold corner A to the crease 3. the kite
One square sheet, two folds, and a kite with a mirror line down its middle.
Why the two sides come out equal: Both folds are made against the same crease, and you fold the same amount on each side. The crease is a mirror line, so whatever happens on the left is copied on the right. That is what makes the two upper sides equal and the two lower sides equal.
Fly it: Tape a thin stick along the crease, tie a thread near the top, add a paper tail at the bottom, and your kite is ready.
Q2.
What shapes do you see in the kite?
Answer

You can see a kite, triangles inside it, and a smaller kite hidden in the folded flaps.

Where to lookShape you seeWhat kind
The whole outlineKite4 sides, two pairs of equal adjacent sides
Either side of the middle creaseTriangleTwo equal triangles, mirror images of each other
Each folded-in flapTriangleA long thin triangle
The two flaps togetherA smaller kiteSitting on top of the big one
The part of the square left behindTriangleThe bottom half of the original square
The mirror line cuts the kite into twoequal triangles The two darker triangles at the top arethe folded-in flaps.
A kite is really two equal triangles put back to back along a mirror line.
Why triangles keep appearing: Every fold you made was a straight line, and a straight cut or fold across a corner always leaves a triangle. That is why paper folding and triangles go together so often.
Open it up: Unfold your kite completely and look at the crease lines on the square. You will see the square divided into triangles — count how many.
