When a straight line standing on a straight line makes the adjacent angles equal to one another, each of the equal angles is right, and the straight line standing on the other is called a perpendicular to that on which it stands.
Tú casa es grande.

The difference between "tú" and "usted" depends on the formality. "Tú" is used <u>when talking to friends or relatives (informal)</u> while "usted" is used <u>when talking to older people or a person of high social rank (formal)</u>.
In this case we want to write the <u>informal</u> form of "tú", so we use "tú". Also, when dealing with <u>permanent states</u>, the verb "ser" (to be) is used.

In general, the imperfect is used to talk about past actions, conditions, or events that occurred regularly or frequently or that were in progress in a moment in the past. It is also used to tell time, talk about dates, give a person's age, and describe features, conditions, and feelings in the past. So we can write the verb in parentheses in the imperfect tense as follows:
1. Ud estaba en la clase de ingles
2. Gloria trabajaba mucho en la tienda de ropa
3. Ellos no eran amigos
4. Ellas iban a la jungla
5. Yo no sabía nada
6. Yo estaba en mexico
7. Tú aprendías mucho
In the imperfect tense, there are only three verbs with irregular conjugations, namely:<em> ir, ser,</em> and <em>ver</em>. The other verbs are regular. Both regular and irregular imperfect verb endings are shown in Tables below.
