Q1MathsUnit 10: Co-ordinate Geometry

An equation for the line that passes through (10,-1) and is perpendicular to

y=\frac{x^{2}}{4}-2

Q2MathsUnit 10: Co-ordinate Geometry

The diagonals of a rhombus bisect each other at

_{\text {一一一一一一一 }}

angles.

Q3MathsUnit 10: Co-ordinate Geometry

Assertion If in a

\triangle A B C,

a line

D E \| B C

intersects

A B

D

and

A C

E,

then

\frac{A B}{A D}=\frac{A C}{A E}

Reason If a line is drawn parallel to one side of a triangle intersecting the other two sides, then the other two sides are divided in the same ratio.
