what of the following basic rules is not true about geometry?
a. a straight line intersecting two parallel lines produces corresponding equal angles
b. similar triangles have the same sides
c. similar triangles have the same angles
d. the sum of the interior angles of any triangle equals 180°
e. none of the above

A. A straight line intersecting two parallel lines produces corresponding equal angles.

Step-by-step explanation:

If two straight lines are parallel, and a straight line intersects them, then we get alternate angles equal, exterior angle equal to the opposite interior angle on the same side and the interior angles on the same sides equal to two right angles.

Hence, here the rule that is not true is : A. A straight line intersecting two parallel lines produces corresponding equal angles.

no he doesnt because "-16' is negatiive

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
