To prove HL you need to prove that the same leg of both of the triangles are congruent and the hypotenuse, and they must be right triangles.

HL- I'd the hypotenuse an a led if a right triangle are congruent to the hypotenuse and a led if another right triangle, then the triangles are congruent.

For SAS, the two sides and the included angle of one triangle are congruent to two sides and the included angle if anther triangle, then the two triangles are congruent.
So you basically need to prove that a side, angle, and a side are congruent......

I really hope that this made sense.....tell me if not.

Answer:

  a) ∠DAE = 33°; ∠ABD = 57°

  b) ∠CEB = 90°

  c) ∠ABE = 22°

  d) ∠ADE = 15°

Step-by-step explanation:

The diagonals of a rhombus meet at right angles. Each bisects the corner angles at its ends. Adjacent angles are supplementary, opposite angles are congruent, and each diagonal creates two isosceles triangles.

a) ∠DAE = 90° - ∠ADE = 90° -57°

  ∠DAE = 33°

  ∠ADE = ∠ABD = 57°

__

b) ∠CEB = 90° . . . . . the diagonals meet at right angles

__

c) ∠ABE = 44°/2

  ∠ABE = 22°

__

d) ∠ADE = 90° -(1/2)∠DAB = 90° -150°/2

  ∠ADE = 15°

Which of the following graphs shows the<br> solution set to 2x &lt; 6 and 3x + 2 &gt;<br> -4?
Ilya [14]

Answer:

The third picture

Step-by-step explanation:

Solve for x in both equations

2x<6

Divide both sides by 2:

x<3

3x+2>-4

Subtract 2 from both sides:

3x>-6

Divide both sides by 3:

x>-2

There is this trick you can use when x is on the left side of the equation to find out which way to shade in you graph. Keep in mind this is only for the left side, it will not work if your variable is on the right.

When the symbol is facing left < then shade left, imagine it is pointing which way to shade. x<3 is represented by the 3 picture on the left. When the symbol is facing right > then shade right, again it is pointing which way to shade. x>-2 is represented by the 3 picture on the right.

The circles are not filled in because the symbol is < and > rather than \leq  and \geq. When it is greater than or equal to or less than and equal to (represented by the line under the symbol), then the circle is shaded in.
