If possible, draw a triangle whose sides measure: a) \(8,9,\) and 10 b) \(8,9,\) and 17 c) \(8,9,\) and 18

Describe the triangle \((\triangle X Y Z,\) not shown) as scalene, isosceles, or equilateral. Also, is the triangle acute, right, or obtuse? $$\mathrm{m} \angle X=43^{\circ} \text { and } \mathrm{m} \angle Y=47^{\circ}$$

One of the angles of an isosceles triangle measures \(96^{\circ} .\) What is the measure of the largest angle(s) of the triangle? What is the measure of the smallest angle(s) of the triangle?

To construct a regular hexagon, what measure would be necessary for each interior angle? Construct an angle of that measure.

To construct a regular octagon, what measure would be necessary for each interior angle? Construct an angle of that measure.

To construct a regular dodecagon (12 sides), what measure would be necessary for each interior angle? Construct an angle of that measure.
