The additional information that could be used to prove ΔABC ≅ ΔDBC

using SAS are;

m∠ABC = 125° and $\overline{AB}$ ≅ $\overline{DB}$ ΔACD is isosceles, with base $\overline{AD}$ $\overline{CD}$ = 52 cm

Reasons:

The given information are;

$\overline{CB}$ bisects ∠ACD

The given information from the diagram are;

$\overline{AC}$ = 52 cm

$\overline{BD}$ = 29 cm

∠CBD = 125°

Solution;

First selected option; m∠ABC = 125° and $\overline{AB}$ ≅ $\overline{DB}$

m∠ABC = 125° and $\overline{AB}$ ≅ $\overline{DB}$

$\overline{CB}$ ≅ $\overline{CB}$ (reflexive property)

ΔABC ≅ ΔDBC (SAS rule of congruency)

Second selected option; ΔACD is isosceles, with base $\overline{AD}$

∠ACB ≅ ∠DCB (definition of angle bisector)

ΔACD is isosceles, with base $\overline{AD}$ (Additional information)

$\overline{CD}$ ≅ $\overline{AC}$ (definition of isosceles triangle)

$\overline{CB}$ ≅ $\overline{CB}$ (reflexive property)

ΔABC ≅ ΔDBC (SAS rule of congruency)

Third selected option; $\overline{CD}$ = 52 cm

∠ACB ≅ ∠DCB (definition of angle bisector)

$\overline{CD}$ = 52 cm = $\overline{AC}$ (given) (additional information)

$\overline{CD}$ ≅ $\overline{AC}$ (definition of congruency)

$\overline{CB}$ ≅ $\overline{CB}$ (reflexive property)

ΔABC ≅ ΔDBC (SAS rule of congruency)

The Side-Angle-Side, SAS, rule of congruency states that two triangles are

congruent if two sides and an included angle of one triangle are

congruent to the corresponding two sides and included angle on the other

triangle.

Answer from: keke6361

Option (1)

Step-by-step explanation:

In the figure attached,

BC is the angle bisector of angle ACD.

To prove ΔABC and ΔDBC congruent by SAS property we require two sides and the angle between these sides to be congruent.

Since BC ≅ BC [Reflexive property]

∠ABC ≅ ∠CBD ≅ 125°

And sides AB ≅ BD

Both the triangles will be congruent.

Therefore, additional information required to prove ΔABC ≅ ΔDBC have been given in option (1).

Therefore, Option (1) will be the answer.

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
