Answer 1

Answer:

1) A Parallelogram has no axes of symmetry and 2 orders of rotation symmetry.

2) SInce they have written draw the figures, I believe you have to draw the different types of Triangles.

3) See the two pairs of lines given on two sides of the triangle? That means those sides are equal. This means that this is an Isosceles Triangle. This also means that the base angles are the same, and the base angles here are 70° and x. That means,

x = 70°.

Now, we know x and z lie on the same planes, and a line has a measure 180°. we know x has taken 70°. We can find z by finding the rest.

x + z = 180°

70 + z = 180°

z = 180 -70

z = 110°.

We know that when all angles of a triangle are added, we get 180°, whatsoever type of triangle it may be. That means,

x + y + 70° = 180

70° + y + 70° = 180

y + 140° = 180

y = 180 - 140

y = 40°.

Now we have got all the values and reasons for it.

x = 70°

y = 40°

z = 110°

Hope it Helps,

Answer 2

Step-by-step explanation:

1. the magnitude of the angle is
2. the y angle is 70 and
3. x angle is 40
4. because x+y+70=180
5. substituting 40+70+70=180
6. the angle of z is = x-180
7. substituting = 40-180
8. = 40
