Translations, rotations, and reflections are rigid transformations. What can you conclude about the measures of sides and angles
attashe74 [19]

Answer:

After a translation, the measures of the sides and angles on any triangle would be the same since translation only involves changing the coordinates of the vertices of the triangle.

After a rotation, the measures of the sides and angles of a triangle would also be the same. Similar to translation, the proportion of the triangle is unchanged after a rotation.

After a reflection, the triangle's sides and angles would still be the same since reflection is a rigid transformation and the proportion of the sides and angles are not changed.

Step-by-step explanation:

Rigid transformations, i.e. translations, rotations, and reflections, preserve the side lengths and angles of any figure. Therefore, after undergoing a series of rigid transformations, the side lengths and angle measures of any triangle will be the same as the original triangle, generally speaking, in another position.

Swanson plans to attempt to swim across the lake from point A to point B as shown below. To determine how far he will have to sw
Ipatiy [6.2K]

Answer:

2.38 miles

Step-by-step explanation:

From Given diagram:

In ΔABC,

AC=2.5 miles

BC= 3.7 miles

∠BCA= 39.4°

Now as we have two sides and an angle, using law of cosines to find the third side:

c= √(a^2+b^2-2abcosα

AB=√(AC)^2 + (BC)^2 - 2(AC)(BC)cosα

    =√(2.5)^2 + (3.7)^2 - 2(2.5)(3.7)cos(39.4°)

    =√(2.5)^2 + (3.7)^2 - 2(2.5)(3.7)(0.77)

   =√(5.695)

     = 2.38 !

0.5 bigger than 9/18
aleksley [76]
No, 0.5 = 9/18.

9/18 can be simplified to 1/2, which is 0.5

Hope this helped! :)
