Missing Measures

100

If Angle A and Angle B are COMPLEMENTARY, and Angle A = 42, what is the measure of Angle B?

A + B = 90

42 + x = 90

x = 48

200

If A and B are SUPPLEMENTARY, and B = 87, what is the measure of angle A?

A + B = 180

x + 87 = 180

x = 93

300

Look at the lines on the board. Line a and b are parallel. If Angle 1 is 75, what is the measure of Angle 8?

1 and 8 are AEA which means they are equal.

Angle 8 = 75

400

Look at the lines on the board. Line a and b are parallel. If Angle 1 is 75, what is the measure of angle 3?

1 and 3 are corresponding angles, they are equal

measure of Angle 3 = 75

500

Look at the lines on the board. Line a and b are parallel. If Angle 1 is 75, what is the measure of angle 4?

Look at the lines on the board. Line a and b are parallel. If Angle 1 is 75, what is the measure of angle 4?

1 and 4 have NO RELATIONSHIP.

BUT 1 and 5 are SUPPLEMENTARY



75 + x = 180

x = 105

5 and 4 are AEA, so the are equal .

Angle 4 = 105

Triangles

100

What kind of triangle has ALL acute angles and two equal sides?

Acute Isosceles Triangle

200

What kind of triangle has a 90 degree angle and no equal sides?

Right Scalene Triangle

300

What kind of triangle has an angle greater than 90 and no equal sides?

Obtuse Scalene Triangle

400

If you added up all the angles in a triangle, what number will you get?

180

500

What do you call the triangle that is near the Caribbean Sea where many ships and planes have disappeared?

The Bermuda Triangle

Missing Measures

100

Triangle ABC.

Angle A = 45

Angle B = 45

Angle C = ??

45 + 45 + x = 180

90 + x = 180

x = 90

200

Triangle ABC.

Angle A = ??

Angle B = 24 Angle C= 36

x + 24 + 36 =180

x + 60 =180

x = 120

300

Triangle ABC. Angle A = 36 Angle B = ?? Angle C = 36

36 + x + 36 =180

72 + x = 180

x = 108
