Answer:

Square and Rectangle

Step-by-step explanation:

This is correct because both sides are parallel and straight so then if you measure all the angles, they would equal 90 degrees.

Answer:

B. Square, Rectangle.

Step-by-step explanation:

The correct answer is B. Square, Rectangle.

A square will always have four equal angles and sides.

A rectangle will not have equal sides, but will always have angles of 90 degrees, as does the square.

Hope this helps!

Jonah tore the angles off a large paper triangle. Then he arranged the three paper angles with their points together so that the
bonufazy [111]

Answer:

Jonah formed a straight angle.

Step-by-step explanation:

  • Acute angle is an angle less than 90 degrees.
  • Obtuse angle is an angle greater than 90 but less than 180 degrees.
  • Reflex angle is greater than 180
  • Straight angle is equal to 180.

We know 3 angles of a triangle (no matter scalene, isosceles, right, equilateral triangle) sum up to 180 degrees. So, if Jonah were to cut of the 3 angles and put them points together, no overlap, he would eventually have a 180 degree angle, or a straight angle.

Jonah formed a straight angle.

Help meeeee;)........​
mylen [45]

Step-by-step explanation:

ABC be the given isosceles right triangle such that <B = 90° , side AC is the hypotenuse; and, AB= BC

Then, (AB)^2 + (BC)^2 = (AC)^2…. Pythagoras theorem.

(AC)^2 = 98 sq. cm. ( given)

So, (AB)^2 + ((BC)^2 = 98

But, AB = BC = a ( say) …. ( given)

Therefore, a^2 + a^2 = 98

Or, 2a^2 = 98.

So, a^2 = 98 / 2 = 49

Hence, a = AB = BC = √49 = 7 cm.

The side AC ( the hypotenuse) = √98 = √(7 *7*2)

= 7 *√2 = 7* 1.414 = 9..898cm., say, 9.9 cm.

Hence, the three sides of the right isosceles triangle are 7 cm, 7cm and ~ 9.9 cm. Answer
