1. Cut a piece of string to a length of about 80 cm. Tie the string in a loop.
Draw a line segment, AB, of length
between 30 cm and 35 cm. Pull the
string to form any triangle, AABC,
along line segment AB.

2 + 2 = 4

Step-by-step explanation:

The question you asked is a simple arithmetic ( addition precisely). Addition is the sum of two or more numbers.

2 + 2 = 4

Depending on your level, you can use counting method ( or the tally system) to get the answer.

2 + 2 = 4

II  + II = IV

I hope this helps you!

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
