Question

construction of an angle of measure 90°,45° with the help of compass​

Answer 1

$\tt {Construction \: of \: 90° \: in \: figure \: 1}$

$\tt {Construction \: of \: 45° \: in \: figure \: 2}$

Answer 2

$\huge{\mathfrak\red{Construction}}$

$\huge{\mathfrak\blue{90°}}$

$\implies\huge{\mathfrak{Use \: a \: compass \: do \: it}}$

${\red {First \: step:-}}$

Draw a line measure 5cm

Put the compass half of it.

The point of the compass should be on the starting of the line segment.

Draw the semi circle on it.

$\pink {Second \: step:-}$

With the same measure.

Keep it on the extreme right of the circle.

Bisect it, by putting an arc.

Then again with the same measure. Bisect it on the other side too.

$\blue {Third \: step:-}$

The first bisection which you did put the needle on it and bisect on the upper region.

Same method to be followed on which you did the second bisection of circle.

Draw a straight line passing through the arcs.

$\purple {Final step:-}$

Use a protractor to measure it and your 90° angle is ready.

$\huge{\mathfrak\red{45°}}$

$\implies\huge{\mathfrak{Use \: a \: compass \: do \: it}}</p><p>$

$\red {First \: step:-}$

Draw a 90° angle with the help of the prodecures given above.

$\pink {Second \: step:-}$

Construct a perpendicular line.

Place compass on intersection point.

Adjust compass width to reach start point.

$\purple {Third \: step:- }$

Draw an arc that intersects perpendicular line.

Place ruler on start point and where arc intersects perpendicular line.

$\blue {Final \: step:- }$

Measure your 45° angle.
